What is the force that keeps an object in motion?
An object which is moving doesn't need a force to keep it moving.
Does a satellite need fuel to keep moving?
Satellites do not need fuel to keep moving because of their inertia and the centripetal force.
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.
What force keeps a space probe moving?
No force is required to keep something moving. According to Newton's Second Law, you need a force to speed something up, or to slow something down - not to keep it moving.
Why do lorries need a force to keep them moving at a steady speed?
They need the force to overcome the friction between the lorry and the road.
What machine reduces the force you need to apply to a bicycle to keep it moving?
The lever.
How much force is needed to move an object?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
How much force is needed to keep a 2kg object moving?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
Newtons second law says to move a mass you need a?
A force. To be precise, a force causes an acceleration - a change in velocity. In theory, if an object is already moving you don't need a force to keep it moving, although in practice, quite often there are frictional forces that slow the object down.
Will 7104 newtons move 4000 pounds?
If there's nothing else holding it back, then any force will move any mass. Andonce you get it moving, you don't need any force at all to keep it moving.
Once the crate is sliding how hard do you push to keep is moving at constant valocity?
You need to push as much as the force of friction is.
Would you need the same force to keep the stone moving as you did to get it started?
This depends upon where the stone is.In a vacuum with no gravitational fields nearby you would need no additional energy to keep a stone flying, the first throw would do it and it would continue until another force acted upon it.To keep a stone moving on the Moon you will need to keep putting in sufficient energy to overcome the gravity there.To keep a stone moving on Earth you would have to keep putting sufficient energy in to overcome a higher gravitational field and the drag caused by the atmosphere.
