What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and its speed.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the edge of a cliff has potential energy.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by two main factors: mass and speed.

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) can be calculated using the formula: KE = 1/2 * mass * speed^2.

Front

What is the relationship between mass and kinetic energy?

Back

As the mass of an object increases, its kinetic energy increases if the speed remains constant.

Front

What is the relationship between speed and kinetic energy?

Back

As the speed of an object increases, its kinetic energy increases exponentially.

Front

Give an example of an object with kinetic energy.

Back

A tennis ball rolling across the court is an example of an object with kinetic energy.

Front

What is the greatest kinetic energy among moving objects?

Back

A car driving down a hill typically has greater kinetic energy than a person running or a ball rolling down the hill.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.
