Energy
The energy an object has because of its motion.
What is kinetic energy?
The matter that a wave travels through.
What is a medium?
A wave that requires matter to travel through.
What is a mechanical wave?
The height of a wave from its resting position.
What is amplitude?
When a wave bounces off a surface.
What is reflection?
Stored energy based on position, height, or arrangement.
What is potential energy?
A disturbance that carries energy from place to place.
What is a wave?
A wave that can travel through space.
What is an electromagnetic wave?
The distance between two crests or troughs.
What is wavelength?
When a wave passes through a material.
What is transmission?
The amount of matter in an object.
What is mass?
In a longitudinal wave, particles pushed close together form this.
What is compression?
A wave where particles move up and down.
What is a transverse wave?
The number of waves passing a point in a given time.
What is frequency?
When a material takes in a wave’s energy.
What is absorption?
Regular Answer: A car and a bus are moving at the same speed, but the bus has more kinetic energy. Explain why.
The bus has more mass.
A wave travels across water, but the water does not move across the ocean. Explain what is actually transferred.
Energy is transferred through the medium.
Sound cannot travel through outer space, but light can. Explain why.
Sound requires a medium, but light does not.
A student increases the amplitude of a wave. Explain what happens to the wave’s energy.
The energy increases.
A straw looks bent in water. Explain what wave interaction causes this effect.
What is refraction?
A ball is lifted higher above the ground while its mass stays the same. Explain how its potential energy changes and why.
The potential energy increases because height/position increases.
A sound wave travels from a classroom speaker to a student’s ears, but the air in the room does not move across the classroom. Explain how the wave transfers energy without transferring matter across the room.
The energy moves through the medium while the particles only vibrate back and forth in place or are temporarily displaced.
A rope wave and a sound wave move differently. Explain how particle motion differs between them.
Rope waves move particles up and down while sound waves move particles back and forth.
One wave has a much higher frequency than another wave. Explain what most likely happens to its wavelength.
The wavelength becomes shorter/decreases.
A wave hits a window and some passes through while some bounces back. Explain how more than one interaction can happen at once.
Waves can both transmit and reflect at the same time.
