What else can I help you with?
How can you find velocity from only force and mass?
You would need to use the equation f=ma In this equation, f means force, m means mass, and a means acceleration. So dividing the force by the mass will give you a figure for acceleration. If you know how long the object has been accelerating for, or how far, and what the initial velocity was (or whether it started off still) then you can work out the velocity from this acceleration.
How does height affect the velocity of a falling body?
A falling object accelerates at a rate of 9.8 m/s2. That means that for every second that it is falling, its velocity increases by 9.8 m/s. The higher that the object is falling from, the longer it will have to speed up, thus the higher its velocity upon impact will be. (This is assuming that it does not reach terminal velocity, the velocity at which an object can no longer accelerate because it is travelling so fast that the drag force (air resistance) is equal to the force of gravity.)
What is positive accelerations?
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
What does Fnet equal?
Fnet, or net force, is the vector sum of all the forces acting on an object. It determines the object's acceleration according to Newton's second law, which states that Fnet = m * a, where m is the mass of the object and a is its acceleration. If the net force is zero, the object remains in its current state of motion, either at rest or moving at a constant velocity.
An object moving at a constant velocity will?
... continue to do that, until a force is exerted on it.
If an object starts to accelerate?
If an object moved with constant acceleration it's velocity must ?
What is true about the forces if you are accelerating?
If you are accelerating, there must be an unbalanced force acting on the object. The net force is what causes acceleration according to Newton's second law, F=ma. If the forces are balanced, then the object will either be at rest or moving at a constant velocity.
If the force acting upon an object are balanced then the object Amust not be moving Bmust be miving with constant velocity Cmust not be accelerating Dnone of these?
If the force acting upon an object are balanced then the object must not be accelerating
When a falling object had stopped accelerating it has reached its?
When a falling object has stopped accelerating, it has reached its terminal velocity. At this point, the force of air resistance acting on the object is equal to the force of gravity pulling it downward, resulting in a balanced force and a constant velocity.
What would you call it when air resistance the force of gravity and a falling object stops accelerating?
When a falling object stops accelerating but is falling at a constant velocity, it is called terminal velocity.
When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
When an object is accelerating are the forces balanced or unbalanced?
When an object is accelerating, the forces acting on it are unbalanced. This means that there is a net force acting on the object in the direction of its acceleration, causing a change in its velocity.
Does an object that has balanced forces or no force acting on it must be stationary?
No. An object that has no net force on it will simply not be accelerating. It can be in motion, but it can not have any change in its velocity.
What happens to an object in free fall as it reaches terminal velocity?
As the object in free fall reaches terminal velocity, it stops accelerating and continues to fall at a constant speed. At this point, the gravitational force pulling the object down is balanced by the air resistance pushing back up, resulting in a net force of zero.
What happens to an object in motion when it experiences a nonzero net force?
its velocity will change by accelerating in the direction of the force
When an object is accelerating?
When an object is accelerating, its velocity is changing over time. This change in velocity can be due to an increase or decrease in speed, a change in direction, or both. The acceleration of an object is directly proportional to the force acting on it, as described by Newton's second law of motion.
When is an object not accelerating?
An object is not accelerating when it is moving in a straight line at an unchanging speed (which may be zero).
