Potential and Kinetic Energy

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object based on its position or state.

Front

When does an object have no kinetic energy?

Back

An object has no kinetic energy when it is at rest.

Front

What is the relationship between potential energy and gravity?

Back

Objects have the potential to fall due to gravity, which affects their potential energy.

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 formula for calculating potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What do potential and kinetic energy have in common?

Back

Both potential and kinetic energy are forms of mechanical energy and are related to the motion and position of objects.

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 factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and its velocity; increasing either will increase the kinetic energy.

Front

Can potential energy be converted to kinetic energy?

Back

Yes, potential energy can be converted to kinetic energy, such as when an object falls from a height.
