What has greater kinetic energy a car traveling at 35 miles per hour or a car traveling at 50 miles per hour?
Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
Which has a greater kinetic energy a car traveling at 30 km h or a car half that mass traveling at 60 km h?
60. K= 1/2mv^2 therefore when v is larger, there is more kinetic energy
Why does an ocean liner traveling at 100km per hour would have more kinetic energy than a yacht traveling at the same velocity.?
The difference is the mass of the moving object: ocean liner some 10.000 to: yacht some 10 to Theory: W kin = kinetic energy m = mass v = velocity W kin = 1/2 * m * v² So the yacht would have to travel approx. 316 times faster than the ocean liner (when at 10 knots per hour) to have the same kinetic energy.
How much work has to be done on a 5 kg sled to increase its speed from 10 m s to 15 m s?
Work is simply a transfer of energy. Calculate the kinetic energy for both speeds, then calculate the difference. The formula for kinetic energy is KE = (1/2)mv2. If the mass is in kilograms, and the velocity (or speed) is in meter/second, the energy is in Joule.
What is the conserved sum of the potential and kinetic energy?
Total energy.
How many times does the kinetic energy of a car increase when traveling 60 mph as opposed to traveling 30 mph?
4 times (from v squared)
What energy is in a traveling bullet?
A traveling bullet primarily carries kinetic energy due to its motion through the air. This kinetic energy is derived from the initial potential energy stored in the bullet when it was fired.
How do you increase the kinetic energy of a skateboard?
Since kinetic energy depends on mass and speed, you can increase either of these.
What is the result of increasing the temp of a gas?
The kinetic energy will increase
How do molecules gain kinetic energy?
Heating increase the kinetic energy.
What does an increase of temperature do to the KE of a liquid?
An increase in temperature of a liquid causes the kinetic energy (KE) of the liquid molecules to increase. This increase in thermal energy leads to faster movement of the molecules, resulting in higher kinetic energy.
How can we calculate the increase in kinetic energy of the pieces during the explosion?
To calculate the increase in kinetic energy of the pieces during an explosion, you can use the formula: Change in kinetic energy final kinetic energy - initial kinetic energy. This involves determining the initial and final velocities of the pieces and plugging them into the formula. The increase in kinetic energy will give you an idea of the energy released during the explosion.
How do you increase the kinetic energy of an object?
To increase the kinetic energy of an object, you can either increase its mass or increase its velocity. Kinetic energy is directly proportional to both mass and velocity, so increasing either one of these factors will result in an increase in the object's kinetic energy.
What makes kinetic energy increase?
Kinetic energy increases with an increase in an object's mass or velocity. The formula for kinetic energy is KE = 0.5 * mass * velocity^2, so either increasing mass or velocity will result in an increase in kinetic energy.
If two bicycles have the same mass but one is traveling at 10 ms and the other is traveling at 15 ms which has more kinetic energy?
The bicycle traveling at 15 m/s has more kinetic energy because kinetic energy is proportional to the square of the velocity. Since the mass is the same for both bicycles, the one traveling faster will have a greater kinetic energy.
Which car has the most kinetic energy?
A car traveling at a higher speed will have more kinetic energy than a car moving at a slower speed. So, the car with the most kinetic energy would be the one traveling at the highest speed.
What causes an increase in the kinetic energy of atoms within an element and an increase in the kinetic energy of molecules or ions within a compound?
An increase in temperature causes an increase in the kinetic energy of atoms in an element. For compounds, an increase in temperature also results in higher kinetic energy of the molecules or ions due to increased movement and collisions among the particles.
