Conservation of Energy: Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can 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 and speed of the object.

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 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 formula for 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

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has, because potential energy is directly proportional to height.

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

In a pendulum, where is the potential energy the highest?

Back

The potential energy is highest at the highest points of the swing (points A and C).

Front

In a roller coaster, how can you increase kinetic energy?

Back

To increase kinetic energy, you can increase the height at the starting point, allowing for more potential energy to convert to kinetic energy.

Front

What type of energy is produced when a bat hits a ball?

Back

When a bat hits a ball, kinetic energy is transferred to the ball, producing sound and thermal energy.
