LEAP Unit 4 Review

Front

Which type of wave requires a medium to travel?

Back

Sound waves require a medium (like air, water, or solids) to travel through.

Front

What type of energy does a golf ball have as it gains height after being hit?

Back

Kinetic energy is the energy of motion; as the golf ball moves upward, it has kinetic energy.

Front

When you do work, you are exerting ____________.

Back

Work is the exertion of force over a distance.

Front

What is an example of a longitudinal wave?

Back

Sound is an example of a longitudinal wave, where the particles of the medium move parallel to the direction of the wave.

Front

Which car has 75 KE (Kinetic Energy) and 25 PE (Potential Energy)?

Back

Car D has 75 KE and 25 PE.

Front

What is the definition of kinetic energy?

Back

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

Front

What is the definition of potential energy?

Back

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

Front

What is a medium in the context of wave travel?

Back

A medium is a substance through which a wave can travel, such as air, water, or solid materials.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, particles move parallel to the wave direction; in transverse waves, particles move perpendicular to the wave direction.

Front

What is the formula for calculating kinetic energy?

Back

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