Magnets and Waves - Pre Learn

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium travel parallel to the direction of the wave.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

At which position does the cart have the MOST potential energy?

Back

Position A has the most potential energy.

Front

What happens to kinetic energy as a roller coaster travels from a high point to a low point?

Back

Kinetic energy increases while potential energy decreases.

Front

What is a magnetic field?

Back

The area of magnetic force around a magnet is known as its magnetic field.

Front

What kind of force do charged particles exhibit?

Back

Charged particles exhibit electromagnetic force.

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

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 the relationship between energy and motion in a roller coaster?

Back

As a roller coaster moves, energy transforms between potential and kinetic forms.

Front

What is the definition of a magnet?

Back

A magnet is an object that produces a magnetic field and attracts certain materials, such as iron.
