-- Measure the force you use to pull the object. You can connect a spring "fish" scale
to the object, pull on the scale, and read off the force while the object moves.
-- Measure the distance the object moves.
Multiply the force by the distance. The product is the energy used to move it.
(Be careful with the units.)
Equal to or greater than the mass of the object under gravity
Any tiny amount of force is enough - assuming there is enough force to overcome any friction forces.
i think its momentum but I'm not sure.....
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.
It takes no force to 'move' an object. There are trillions of objects that are moving right now with no forces acting on them. It only takes force to 'accelerate' an object ... to change its motion, by changing its speed or the direction of its motion. force=mass*acceleration As mass increases, so does the force needed to change the object's motion.
Speed and direction of motion are needed to determine velocity.
how does moving a fulcrum on a lever change the amount of force needed to move an object
an unbalanced force

. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
motion.
A Reference Point A reference point is needed to determine if an object is in motion.

force of compression
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.
Speed and direction of motion are needed to determine velocity.
Inertia is the tendency of an object to resist a change in its motion. Objects with more mass have more inertia. The more mass an object has the harder it is to change its motion. Thats is how inertia effects and object. (Don't worry I got this from my Science Textbook)
