6.8A Potential and Kinetic Energy Questions

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 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 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, demonstrating the conversion of energy.

Front

What is an example of potential energy?

Back

An example of potential energy is a rock held at the top of a hill. It has the potential to roll down.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a moving car. The faster it moves, the more kinetic energy it has.

Front

At what point is potential energy the highest for a diver?

Back

A diver has the most potential energy at the top of the diving board before jumping.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, depending on the object's motion and position.

Front

What is an example of energy conversion?

Back

An example of energy conversion is a book falling off a shelf, where potential energy is converted into kinetic energy.
