A force exerted over a distance to move an object is ______________________.

A 5000N block is lifted 10 m. How much work was done?

In which of these cases is work being done?

Work done by the force of friction

when a body slides against a rough horizontal surface, the work done by friction is

If a force acts perpedicular to the direction of motion of a body, what is the amount of work done?

What is the sign of the work done by gravity on a man standing on a platform?

What is the sign of the work performed on an object in uniform circular motion?

A constant force of 10 N causes a box to move at a constant speed of 2 m/s. How much work is done in 10 seconds?

A horizontal force of 5 N is required to maintain a velocity of 2 m/s for a block of 10 kg
mass sliding over a rough surface. Calculate the work done by this force in one minute.

A force F = (5i – 3j +2k) N moves a particle from r1 = (2i + 7j + 4k) m to r2 = (5i + 2j + 8k) m. What is the work done by the force?

The area under the force (F) versus displacement (x) graph gives work.

A force F = x + 1 N acts on a particle in x direction. What is the work done from x = 2m to 5 m?

In situations involving non conservative external force, the work done by these forces:
