What would be the amount of work done on an object by a force,if the displacement of the object is zero?

How are kinetic energy and momentum related?

What is the work done by the earth in moving around the sun?

The speed of a particle is doubled,its kinetic energy:

Justify,giving proper reasoning,whether the work done in the following case is positive or negative: Work done by the resistive force of air on a vibrating pendulum in bringing it to rest.

Define $1\, W$ of power. $A$ lamp consumes $1000\, J$ of electrical energy in $10\, s$. Calculate its power.
