Potential Energy & Kinetic Energy CFU

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

True or False: Kinetic energy increases with speed.

Back

True. The faster an object moves, the more kinetic energy it has.

Front

What type of potential energy is stored in food?

Back

Chemical potential energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, often referred to as heat.

Front

What is the relationship between kinetic energy and mass?

Back

Kinetic energy is directly proportional to the mass of the object; as mass increases, kinetic energy increases if velocity remains constant.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is an example of gravitational potential energy?

Back

A rock held at a height above the ground has gravitational potential energy due to its position.
