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 is the energy that 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 speed at which it is moving.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has. This is because potential energy is calculated as mass times gravity times height (PE = mgh).

Front

What is the formula for kinetic energy?

Back

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

Front

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

Back

A ball at 3 meters has more potential energy because it is higher above the ground.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to friction.

Front

What is the relationship between potential and kinetic energy in a roller coaster?

Back

In a roller coaster, potential energy is highest at the top of the hills, and kinetic energy is highest at the bottom of the hills.

Front

Does mass affect kinetic energy?

Back

Yes, the mass of an object directly affects its kinetic energy. A heavier object moving at the same speed has more kinetic energy than a lighter object.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground, influenced by gravity.

Front

When is kinetic energy greatest in a swinging pendulum?

Back

Kinetic energy is greatest at the lowest point of the swing, where the speed is highest.
