What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

How can you increase the kinetic energy of an object?

Back

You can increase the kinetic energy of an object by making it move faster.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a stretched rubber band has potential energy.

What happens to the pitch of a sound when the string is shorter?

Back

Shorter strings create a higher pitch sound.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). For example, warm air rising and cool air sinking.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, a metal spoon getting hot when placed in a hot soup.

What is an example of kinetic energy in everyday life?

Back

A spinning bicycle wheel is an example of kinetic energy.

What is an example of potential energy in everyday life?

Back

A rubber band pulled tight without releasing it is an example of potential energy.

Front

What is the relationship between mass and kinetic energy?

Back

Increasing the mass of an object while keeping its speed constant increases its kinetic energy.

Front

What is the formula for kinetic energy?

Back

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