Question

The product of force and displacement equals:
A.Work
B.Power
C.Momentum
D.None of these

Answer 1

Hint: In this question we have to find the result of the product of force and displacement. To solve this question we must have the knowledge of force and displacement and the knowledge of basic formulae is must. To understand this question we will see the explanation below.

Complete step by step answer:
Force- When there is a pull or push on any object due to interaction of two objects then there will be a change in the position of the object. This change is due to a force applied by one object on another object.
Displacement- Displacement is the change in the position of any object. Displacement is a vector quantity. The unit of displacement is meter.
Work is defined as the dot product of force and displacement. The unit of work is joule.
W=F.d
Power is work done per unit time. The unit of power is watt.
P=W/t
Momentum is defined as the product of mass and velocity. The unit of momentum is kg-m/s.
p=mv
Hence, from the above explanation it is clear that work is the product of force and displacement.
Result- Hence, from the above explanation it is clear that the product of force and displacement is equal to work.
Hence, option (A) is correct.

Note:
In this type of questions, we must have the knowledge of the definitions of the variables. The formulae of the variable must also be there. We can verify the answer by the unit of variables. We should check all the options given in the question before giving the answer.
