With changing the "state of motion", I assume you want to change the velocity. What you need here is a force, applied on the object. The amount of acceleration is given by Newton's Second Law.
Inertia is the motion that acts on an object.
it's force the action that has the ability to change an objects motion...
you need a net force to be applied
You will need an external force.
it is called inertia
Any net force
Gravitational Energy
when the forces are balanced ,means a net external force is applied the object continues to be in the same state of rest or of motion
property of a body that requires force to change its state of motion
it takes an unbalanced force to change an object's state of motion
it is called inertia
yes every unbalanced force can change or "try to change (can be or cannot be)" the state of rest or motion
Any net force
All objects resist changes in their state of motion
Motion is change of position. but remember both must always be related to some 'datum' position or state of motion.
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Gravitational Energy
when the forces are balanced ,means a net external force is applied the object continues to be in the same state of rest or of motion
If there is zero net force on an object, the object will not accelerate. (It's velocity will not change.)
It changes its state of motion.
Force, can change the state of motion through acceleration a=Force/m.
