|---|---|---|---|---|---|
| What is a wave? | A disturbance that transfers energy.
🗑
|
||||
| What is a Transverse wave? | Particles that move perpendicularly the direction the waves travel
🗑
|
||||
| What is a medium? | A liquid, solid, or gas that a wave can travel through.
🗑
|
||||
| What is the Crest of a wave? | The highest point on a wave.
🗑
|
||||
| What is the trough of a wave? | The lowest point on a wave.
🗑
|
||||
| What is a longitudinal wave? | Particles that move back and forth in the same direction as the wave is traveling.
🗑
|
||||
| What is compression? | Where particles in a wave are packed together tightly.
🗑
|
||||
| What is rarefaction? | Where particles in a wave spread apart.
🗑
|
||||
| What is a mechanical wave? | A wave that requires a medium.
🗑
|
||||
| What is a electromagnetic wave? | A wave that doesn't require a medium.
🗑
|
||||
| What is amplitude? | How far the wave is from the resting point to the crest or trough.
🗑
|
||||
| What is a wave length? | The distance from one exact same spot on a wave to another. Examples are crest to crest or trough to trough.
🗑
|
||||
| What is frequency? | The number of waves that pass a point in a certain amount of time.
🗑
|
||||
| What is a Hertz? | What we use to measure frequency.
🗑
|
||||
| What is wave speed? | The speed the waves travel at.
🗑
|
||||
| What is force? | A push or pull upon an object in order to change that objects motion. Measured in Newtons (N)
🗑
|
||||
| What is work? | The use of force to move an object a certain distance. Measured in Joules (J).
🗑
|
||||
| What is power? | The amount of work used in a certain amount of time. Measured in Watts (W).
🗑
|
||||
| A man tries to put a elephant on a escalator. The elephant weighs 3000N. The escalator lifts it 10 meters in 120 seconds. How much power was used? | P = 250
🗑
|
||||
| A group of football players applying a force of 2400 N to move a football sled 15 meters. What amount of work will they have accomplished? | W = 36,000 J
🗑
|
||||
| What needs to change in a work equation to decrease the work value? | The distance needs to decrease and the force needs to decrease.
🗑
|
||||
| What needs to change in a power equation to increase the power value? | The work needs to increase and the amount of time it takes needs to decrease.
🗑
|
||||
| What needs to change in a power equation to alter the power value? | The work needs to either increase/decrease or the amount of time it takes needs to increase/decrease.
🗑
|
||||
| What is a difference between transverse waves and longitudinal waves? | Transverse waves move back and forward while longitudinal waves move parallel.
🗑
|
||||
| Does a mechanical wave need a medium to travel? | Yes. Without a medium mechanical waves can not move.
🗑
|
||||
| Does a electromagnetic wave need a medium to travel? | No. Light can travel through empty space and light is an example of electromagnetic waves.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
