Amplify Magnetic Fields Chapter 2

Front

What is the force in a slingshot?

Back

Elastic force.

Front

True or False: A magnetic force is needed to store potential energy in a magnetic field.

Back

True.

Front

Why does an egg have potential energy?

Back

The gravitational force pulls on the egg, transferring potential energy into the gravitational field around the egg.

Front

What happens to the potential energy of an egg when it is lowered closer to the earth?

Back

It has less potential energy.

Front

When magnets are held in place and not allowed to attract or repel, do they have potential or kinetic energy?

Back

Potential energy.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has due to gravitational force.

Front

What is the formula for gravitational potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the role of elastic force in a slingshot?

Back

Elastic force allows the slingshot to store energy when stretched and release it to propel an object.
