Want this question answered?
yes.
Elastic potential energy is gained the more it is stretched (like a catapault or rubber band) Gravitational potential energy is increased if the object is raised higher up (further away from the centre of gravity)
False.
Work is done when force causes an object to move and capacity of doing work is called energy So, energy is required and consumed when force causes an object to move
When negative work is done on the object, the object's energy decreases. This MAY be kinetic energy, but some other form of energy may increase instead, for example, potential energy or heat energy.
yes.
Generally yes, but it really depends on the specific situation. -- If the work is done to lift the object, then the object's potential energy is increased. -- If the work is done to accelerate the object, then the object's kinetic energy is increased. -- If the work is done to move the object against friction, then the energy supplied is dissipated, and the object's energy may or may not change, depending on whether or not it is somewhat heated by the dissipation.

Energy!
the Work-Energy Theorem states the work done is equal to the change in kinetic energy.
