Chapter 2 Review Flashcard

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or arrangement. It has the potential to do work when the object's position changes.

Front

What happens to Potential Energy when a magnet is moved against the magnetic force?

Back

The potential energy increases because the magnet is being moved against the force that is trying to pull it back.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy that an object has because it is moving. The faster an object moves, the more kinetic energy it has.

Front

What does it mean to 'Repel' in terms of magnetic forces?

Back

To repel means to push objects away from one another. In magnets, like poles repel each other.

Front

What does it mean to 'Attract' in terms of magnetic forces?

Back

To attract means to pull objects towards one another. In magnets, opposite poles attract each other.

Front

What is the term for moving energy from one object to another?

Back

Transfer is the term used to describe moving energy from one object to another.

Front

What is the relationship between distance moved and Potential Energy?

Back

The greater the distance an object is moved against a force, the greater the increase in potential energy.

Front

What is the effect of moving a cart towards a magnet?

Back

Moving a cart towards a magnet increases its potential energy as it is moving against the magnetic force.

Front

What is the formula for calculating Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is an example of Potential Energy in everyday life?

Back

A book on a shelf has potential energy because of its height above the ground.
