Work and Energy_SRM 1

What is the explanation of work in terms of physics?

• The product of the force applied to an object and the distance over which the force is applied.

• The temperature of an object

• The amount of time spent on a task

• The speed at which an object moves

What is the formula of work done in physics?

• W = F x d

• W = F / d

• W = F + d
