Where does kinetic energy go after it is used?
If you're suggesting something like an auto accident, the energy of the collision is used to deform materials in the structural elements of the vehicle(s). It also heats them. The primary design features of cars includes a lot of thought to where the energy of a collision can go. Bumpers collapse, body panels and their strengthening members fold and become compressed, and a top or roof can collapse down. All this sinks ("sucks up") energy. And if it all works in an optimal way, you can climb out and walk away.
Comparison between elastic and inelastic collision?
In an elastic collision, all initial kinetic energy is fully restored as final kinetic energy. where nothing is converted into noise, heat or any other form of energy. In an inelastic collision, kinetic energy is "lost" to thermal or sound energy.
Apply Newton's 3 law of motion to explain how 2 billiard balls moving toward each other at the same speed collide and move away from each other at the same speed as before?
Newton's Third Law states that if object A (let's call it the cue ball) exerts a force on object B (let's call it the eight ball), then the eight ball will exert an equal and opposite force on the cue ball. If the cue ball is in motion and heads toward the eight ball which is in motion toward the cue ball, they will collide. Both balls will exert the same amount of force on each other, but in opposite directions (Newton's 3rd law). Since both balls have the same mass and have the same magnitude of force acting on them, they will both accelerate at the same rate (this is actually now entering into Newton's 2nd law). a=F/m
Did Isaac Newton make Newton Balls?
I can not tell you why he made it but I can tell you about it. Newton's cradle can be modeled with simple physics and minor errors if it is incorrectly assumed the balls always collide in pairs. If one ball strikes 4 stationary balls that are already touching, the simplification is unable to explain the resulting movements in all 5 balls, which are not due to friction losses. For example, in a real Newton's cradle the 4th has some movement and the first ball has a slight reverse movement. All the animations in this article show idealized action (simple solution) that only occurs if the balls are not touching initially and only collide in pairs.
Can potential energy ever be less than kinetic energy?
The answer to both of your questions lies in the different nature of both quantities, momentum and kinetic energy. Momentum is a vector, kinetic energy is a scalar. This means that momentum has a magnitude and a direction, while kinetic energy just has a magnitude. Consider the following system: 2 balls with equal mass are rolling with the same speed to each other. Magnitude of their velocities is the same, but the directions of their velocities are opposed. What can we say about the total momentum of this system of two balls? The total momentum is the sum of the momentum of each ball. Since masses are equal, magnitudes of velocities are equal, but direction of motion is opposed, the total momentum of the system of two balls equals zero. Conclusion: the system has zero momentum. What can we say about the total kinetic energy of this system? Since the kinetic energy does not take into account the direction of the motion, and since both balls are moving, the kinetic energy of the system will be different from zero and equals to the scalar sum of the kinetic energies of both balls. Conclusion: we have a system with zero momentum, but non-zero kinetic energy. Assume now that we lower the magnitude of the velocity of one of the balls, but keep the direction of motion. The result is that we lower the total kinetic energy of the system, since one of the balls has less kinetic energy than before. When we look to the total momentum of the new system, we observe that the system has gained netto momentum. The momentum of the first ball does not longer neutralize the momentum of the second ball, since the magnitudes of both velocities are not longer equal. Conclusion: the second system has less kinetic energy than the first, but has more momentum. If we go back from system 2 to system 1 we have an example of having more kinetic energy, but less momentum. I hope this answers your question Kjell
When 2 balls collide the momentum of the balls after the collision is explained by?
the law of conservation of momentum, which states that the total momentum in a closed system remains constant before and after a collision. This means that the combined momentum of the two balls after the collision is equal to the momentum of the two balls before the collision.
What happens to all the momentum when two billiard balls?
The momentum stays the same.
What happens to all the momentum when two billiard balls collide.?
In a collision between two billiard balls, momentum is conserved. This means that the total momentum of the two balls before the collision is equal to the total momentum after the collision. The momentum is transferred between the two balls during the collision, resulting in changes in their individual velocities.
How will balls move if they collide and stick together?
Consevation of momentum applies. The final compond mass must have the same momentum as the net momentum of the two balls before the collision. Remember, momentum is a vector and direction is important. For example if the two balls are moving toward each other with the same momentum, the net momentum is zero because they are moving in opposite directions. So the compound ball will not move. Or, if ball 1 is moving left and has a greater momentum then ball 2 ,moving right, then the compound ball will move left. Its momentum will equal the difference between the two momentums because when you add two vectors in opposite directions you subtract their magnitudes. Mechanical energy (potential + kinetic) is not conserved in this collision because some mechanical energy is lost as heat in the collision.
When two billiard balls collide the total change in momentum is what?
When two billiard balls collide, the total change in momentum is equal to zero according to the law of conservation of momentum. This means that the combined momentum of the two balls before the collision is equal to the combined momentum after the collision.
Two balls of masses 500gram and 200 gram are moving at valocities 4m s and 8m s respectively on collision they stick together find the velocity af the system after collision?
To find the velocity of the system after the collision, we can use the principle of conservation of momentum. The total momentum before the collision is equal to the total momentum after the collision. Total momentum before collision = (mass1 * velocity1) + (mass2 * velocity2) Total momentum after collision = (mass_system * velocity_final) Using these equations, you can calculate the final velocity of the system after the collision.
How can you show that momentum is not conserved between the balls when friction is strong?
If momentum is not conserved between the balls when friction is strong, you can show it by performing an experiment where two balls collide on a rough surface. Measure the momentum before and after the collision and observe if the total momentum changes. If the momentum changes, it indicates that momentum is not conserved due to the influence of strong friction during the collision.
Describe what happens to the momentum of two billiard balls that collide?
They have identical momentum before the collision . The total momentum will the the same before and after the collision. When the balls collide they will bounce apart both with same force and so the same momentum as originally - but in opposite directions. This assumes no energy loss in an ideal elastic collision.
What is an elastic collision with balls?
An elastic collision between balls is one in which both kinetic energy and momentum are conserved. This means that the total kinetic energy of the system before the collision is equal to the total kinetic energy after the collision, and the total momentum remains constant. In an elastic collision, the balls do not stick together and there is no loss of kinetic energy due to factors like friction or heat.
Billiard balls colliding is an example?
An example of the principle of conservation of momentum, which states that the total momentum of an isolated system remains constant before and after a collision.
What is the total momentum of the system before collision If two 0.5 kg balls approach each other with the same speed of 1.0 ms?
Momentum is mass times velocity. But in this case, you don't even need to calculate that: If I understand correctly, the balls have the same mass, the same speed, and they move exactly in opposite directions - so any momentum from one ball is exactly offset by the momentum of the other ball. In other words, if one ball has a momentum of +M, the other one will have a momentum of -M.
How do different surfaces affect the change of momentum for different types of balls and What are the factors affecting the momentum of different objects during collision an How is momentum conserved?
Different surfaces affect the change of momentum by influencing the coefficient of restitution, which determines how much kinetic energy is conserved during a collision. Factors affecting momentum during collisions include mass, velocity, and angle of collision. Momentum is conserved in collisions because there is no external force acting on the system, so the total momentum before the collision is equal to the total momentum after the collision.
