Work and Energy Basics

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is the formula for gravitational potential energy?

Back

GPE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is work in physics?

Back

Work is a force applied to an object that results in a displacement in the same direction.

Front

What is the unit of work?

Back

The unit of work is Joules.

Front

What is the unit of force?

Back

The unit of force is Newtons.

Front

What type of energy is associated with an object's height?

Back

Gravitational potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = ½mv², where m is mass and v is velocity.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in its energy.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
