6.8A 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 has the potential to do work when released.

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 its velocity.

Front

How is potential energy calculated?

Back

Potential energy (PE) can be calculated using the formula: PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How is kinetic energy calculated?

Back

Kinetic energy (KE) can be calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

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

At what point does an object have maximum potential energy on a roller coaster?

Back

An object has maximum potential energy at the highest point of the roller coaster.

Front

At what point does an object have maximum kinetic energy on a roller coaster?

Back

An object has maximum kinetic energy at the lowest point of the roller coaster.

Front

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

Back

In a swing, potential energy is greatest at the highest points, while kinetic energy is greatest at the lowest point.

Front

When does a skateboarder have the most potential energy?

Back

A skateboarder has the most potential energy at the top of the ramp.

Front

When does a skateboarder have the most kinetic energy?

Back

A skateboarder has the most kinetic energy at the bottom of the ramp.
