Amplify Magnetic Fields Chapter 2

Front

What is the elastic force?

Back

The elastic force is the force exerted by a material when it is stretched or compressed, returning to its original shape.

Front

Where is potential energy stored in a slingshot?

Back

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

Front

How does moving a magnet away from another magnet affect potential energy?

Back

Moving a magnet away from another magnet increases the potential energy between them.

Front

Which object has more kinetic energy: an egg or a watermelon?

Back

The watermelon has more kinetic energy because it has more mass.

Front

What happens to the energy of a vehicle going up a hill?

Back

The potential energy increases while the kinetic energy decreases.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

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

Front

Explain the relationship between mass and kinetic energy.

Back

Kinetic energy increases with mass; the more mass an object has, the more kinetic energy it can have at a given speed.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 * mass (m) * velocity (v)^2.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.
