Answer 2

Answer:

• A force is a push, pull or a twist which has a tendency to change the shape, state of rest or of uniform motion of the body on which it has been applied.  it's SI unit is kg m /s² or Newton.

• Work is said to be done when a force produces a displacement in the body and acts in any direction except perpendicular to the direction of displacement.  Work = Force× Displacement

• energy is the ability of a physical system to produce changes on other physical systems. Examples of energies are: light, sound, heat etc. The S.I. unit of energy is joules (J).
