Kinetic and Potential Energy

Front

What is the definition of potential energy?

Back

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

Front

What is kinetic energy?

Back

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

Front

At which point is potential energy greatest in a roller coaster?

Back

At the highest point of the track.

Front

How does increasing an object's speed affect its kinetic energy?

Back

Increasing an object's speed increases its kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

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

Back

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

Front

At what position does a rock have the greatest kinetic energy when thrown?

Back

At the lowest point of its trajectory.

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 an object possesses due to its height above the ground.

Front

How can potential energy be converted into kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object is allowed to move downward due to gravity.
