Questions and Answers

What is the relationship between force and energy?

Force and energy are independent of each other.
More force results in lesser energy needed.
More force results in more work done, thus more energy needed. (correct)
Energy can be increased without applying any force.

A small force is always sufficient to move a heavy object.

False (B)

Force

A push or pull that can cause an object to move or change its motion.

Energy

The ability to do work. It's what's needed to move something.

Work

The amount of force applied multiplied by the distance an object moves. It's a measure of how much energy is transferred.

Force, Work, and Energy Relationship

The relationship between force, work, and energy. The more force you need, the more work you do, and therefore the more energy you use.
