Force

• Work is a scalar product of force vector F and displacement s and hence work is a scalar quantity. Impulse, force and acceleration are vector quantities since they specify the direction while work done is a scalar quantity. There is no direction in which the work is done. Work done W = F s.

Answer 2

Ur answer :-

(i) Force. » A force is a push or pull upon an object resulting from the object's interaction with another object.

(ii) Energy » Energy is the capacity to do work .

(iii) Acceleration » Acceleration the change in the velocity vector in a time interval, divided by the time interval.

(iv) Torque » Torque is a twisting force that speaks to the engine's rotational force and measures how much of that twisting force is available when an engine exerts itself.

hope it helps you....
