Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
Why is less force needed to keep an object moving than to start the object in motion?
1). Because maintaining an object in motion requires no force, but causing a non-moving object to move involves acceleration which does require force. 2). Because kinetic friction is generally less than static friction.
What is the force that keep an object moving?
gravity
What is the tendency of a moving object to keep moving in a straight line?
It is called inertia.
What force must you overcome to start an object moving?
Friction. Specifically, static friction. After the object begins to move, it will still be necessary to overcome rolling or sliding friction to keep it in motion.
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
Is it true that to keep an object moving a force must be apllied?
No, it is untrue. No force is required to keep a moving object moving.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
Why a horse has to apply more force to start a Tonga than to keep is moving?
Because of friction. Every object has 2 friction coefficient values (called Mu and with its own symbol) - one stationary, and the other while the object is moving. It always takes more force (N) to move an object from a stand-still then it does to keep the same object moving.
Is force always neede to keep an object moving?
Force is never needed to keep an object moving unless there is an opposite force trying to slow the object.
Why is less force needed to keep an object moving than to start the object in motion?
1). Because maintaining an object in motion requires no force, but causing a non-moving object to move involves acceleration which does require force. 2). Because kinetic friction is generally less than static friction.
What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
When forces are not balanced an object may keep object moving forever true or false?
That's true. Plus ... even if the forces on an object are BALANCED, it can keep moving forever.
No force is necessary to?
to keep an object moving the way it is already moving .
What is the force that keep an object moving?
gravity
Why is it really hard to push a car to start moving it but it is easy to push it to keep it moving?
newtons first law. An object in motion stays in motion. Its inertia keeps it going
What is the tendency of a moving object to keep moving in a straight line?
It is called inertia.
