6.8A Potential and Kinetic Check Point

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, an apple hanging from a tree has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does potential energy change to kinetic energy?

Back

Potential energy converts to kinetic energy when an object moves from a higher position to a lower position, such as an apple falling from a tree.

Front

Which has more kinetic energy: a moving truck or a moving bicycle at the same speed?

Back

The moving truck has more kinetic energy because it has a greater mass than the bicycle.

Front

What happens to kinetic energy when an object comes to a stop?

Back

When an object comes to a stop, its kinetic energy is transformed into other forms of energy, such as heat due to friction.

Front

What is an example of potential energy in everyday life?

Back

A stretched rubber band has potential energy because it is stored energy that can be released when the band is let go.

Front

What is the relationship between height and potential energy?

Back

The higher an object is positioned, the more potential energy it has due to the gravitational force acting on it.

Front

What is an example of kinetic energy?

Back

A rolling ball is an example of kinetic energy because it is in motion.

Front

How does energy change when cycling up a hill?

Back

As a cyclist goes up a hill, kinetic energy is converted into potential energy due to the increase in height.

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.
