Kinetic and Potential Energy Review

Front

What is the definition of kinetic energy?

Back

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

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

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is the formula for calculating gravitational potential energy?

Back

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

Front

How do kinetic and potential energy relate to each other in a pendulum?

Back

In a pendulum, potential energy is converted to kinetic energy as it swings down, and kinetic energy is converted back to potential energy as it swings up.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the joule (J).

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What do kinetic and potential energy have in common?

Back

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

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy is directly proportional to mass; as mass increases, kinetic energy increases if velocity remains constant.
