Energy Transformations

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What are the two main types of energy?

Back

Kinetic energy (energy of motion) and potential energy (stored energy).

Front

What happens to potential energy as an object falls?

Back

Potential energy decreases while kinetic energy increases.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; the more mass an object has, the more kinetic energy it has at the same speed.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of energy transformation?

Back

A rubber band-powered boat transforms potential energy into kinetic energy.
