400

Sound waves are this type of wave.

What is longitudinal?

200

In this type of collision, kinetic energy is conserved.

What is an elastic collision?

300

What is to the left?

400

For an object swung in a circle on a rope in the vertical plane at a constant speed, this is the point in its travel where the tension in the string will be at a maximum.

What is at the bottom of the circle?
