kenetic and potential energy

Front

What is potential energy?

Back

The energy an object has due to its position or condition.

Front

When does a yo-yo have the most potential energy?

Back

When it's at its highest point.

Front

What is energy?

Back

The ability to do work.

Front

When a pendulum swings, at which point is potential energy at its greatest?

Back

At the highest point of the swing.

Front

What is stored energy called?

Back

Potential energy.

Front

What is kinetic energy?

Back

The energy an object has due to its motion.

Front

How is kinetic energy calculated?

Back

Kinetic energy is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What happens to potential energy as an object falls?

Back

Potential energy decreases while kinetic energy increases.

Front

What is the relationship between potential and kinetic energy in a closed system?

Back

In a closed system, the total mechanical energy (potential + kinetic) remains constant.

Front

At what point in a roller coaster does potential energy convert to kinetic energy?

Back

At the lowest point of the track.
