Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its speed.

Front

How does mass affect kinetic energy?

Back

The kinetic energy of an object increases with its mass. More mass means more energy when moving at the same speed.

Front

What happens to kinetic energy when speed is doubled?

Back

When the speed of an object is doubled, its kinetic energy quadruples.

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.

Front

What is the relationship between kinetic energy and speed?

Back

The relationship is quadratic; as speed increases, kinetic energy increases exponentially.

Front

Can kinetic energy be converted to potential energy?

Back

Yes, kinetic energy can be converted to potential energy, such as when an object is lifted against gravity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

Which has more potential energy: a ball at 3 meters or a ball at 1 meter?

Back

A ball held at 3 meters has more potential energy than a ball at 1 meter.

Front

What factors affect potential energy?

Back

Potential energy is affected by the height of the object and the mass of the object.
