Potential and 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

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height of the object above the ground and its mass.

Front

What is the formula for calculating 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 unit of measurement for potential energy?

Back

The unit of measurement for potential energy is Joule.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the greater its potential energy due to the increased gravitational force acting on it.

Front

What happens to kinetic energy as speed increases?

Back

As the speed of an object increases, its kinetic energy increases exponentially, since it is proportional to the square of the speed.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, especially in systems like roller coasters or pendulums.

Front

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

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass; a heavier object moving at the same speed has more kinetic energy than a lighter object.
