Question

work done in an object by a force would be zero if the displacement of the object is _______​

Answer 1

Answer:

zero

Explanation:

work=force ×displacement

if,displacement =0

then,

work=force ×0

work=0

Answer 2

Work done in an object by a force would be zero if the displacement of the object is zero.

• Work is said to be done, only if there is a displacement due to the application of force.
• Hence, work is said to be the product of the force applied and the resultant displacement.
• Work done = Force x Displacement
• There are three situations when the work done could be zero.
• One is when the force applied and displacement is perpendicular to each other.
• The other two situations are when either force or displacement is zero.
• Here a force is being applied but the work is zero, this indicates that the displacement is zero.
