Amplify Magnetic Fields Chapter 2

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 when the object is in motion.

Front

Where is potential energy stored in a slingshot?

Back

The potential energy is stored in the elastic of the slingshot when it is stretched.

Front

What type of energy do magnets have when they repel each other?

Back

When magnets repel each other, they have kinetic energy as they move away from each other.

Front

How does the height of an object affect its potential energy?

Back

The higher an object is positioned, the greater its potential energy due to the gravitational force acting on it.

Front

What happens to potential energy when a magnet is moved away from another magnet?

Back

The potential energy increases because you are moving the magnet against the magnetic field.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the mass and speed of an object.

Front

How is kinetic energy calculated?

Back

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

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass or speed; doubling the mass or speed increases the kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A drawn bow has potential energy stored in the stretched string.

What is an example of kinetic energy in everyday life?

Back

A moving car has kinetic energy due to its motion.
