Energy: Potential & Kinetic and Thermal energy

Front

What happens to the average kinetic energy of particles when the temperature of a substance increases?

Back

The average kinetic energy of its particles increases.

Front

What occurs when you touch something that feels cold?

Back

Heat from your hand moves into the cold substance.

Front

How does the thermal energy of an object relate to its temperature?

Back

The higher temperature an object has, the more thermal energy it has.

Front

What happens to the particles in a popsicle when it melts?

Back

The particles in the popsicle gain thermal energy and speed up.

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created or destroyed, only transformed or transferred.

Front

Define potential energy.

Back

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

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object in motion.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

How can energy be transformed?

Back

Energy can be transformed from one form to another, such as potential energy to kinetic energy.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height.
