Potential energy can be defined as...
Energy held by an object because of its position relative to other objects

A quantity that has neither direction or magnitude
None of these options
The Law of Conservation of Momentum can be defined as...
A quantity that has neither direction or magnitude
Encounter between two bodies in which the total kinetic energy of the two bodies remains the same
The quantity that characterizes motion of which never changes in an isolated collection of objects
None of these options
Kinetic energy can be defined as...
Stored energy
Energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity
Direction of force over time in relation to momentum
None of these options
Impulse can be defined as...
Integral of a force, F, over the time interval, t, for which it acts, vector quantity
The quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant
