|---|---|---|---|---|---|
| energy | the ability to do work
🗑
|
||||
| work | the product of force and the distance over which it moves
🗑
|
||||
| motion | a constant change in the location of a body
🗑
|
||||
| speed | Distance traveled divided by the time needed to travel that distance
🗑
|
||||
| wave | a disturbance that moves through a medium
🗑
|
||||
| wavelength | The length of a single cycle of a wave, as measured by the distance between one peak or trough of a wave and the next
🗑
|
||||
| amplitude | the maximum height of the wave crest above the rest position or the maximum depth of the wave trough below the rest position
🗑
|
||||
| frequency | the number of waves that pass a single point in a given amount of time
🗑
|
||||
| kinetic energy | Energy of motion
🗑
|
||||
| potential energy | Stored energy
🗑
|
||||
| weight | the force of gravity acting on a mass
🗑
|
||||
| force | A push or a pull; has a size and direction
🗑
|
||||
| friction | Any force that resists motion
🗑
|
||||
| unbalanced force | Unequal forces acting on an object – results in a change in the object’s motion in the direction of the larger force
🗑
|
||||
| balanced force | Describes forces that are equal but opposite in directions; cancel each other out and no change in motion occurs
🗑
|
||||
| acceleration | Change in velocity divided by the amount of time needed for that change to take place; speeds up, slows down or changes direction
🗑
|
||||
| thermal energy | The total energy of all the particles in a sample of matter
🗑
|
||||
| chemical energy | Energy produced by a chemical reaction or chemical change
🗑
|
||||
| mechanical energy | the energy which is possessed by an object due to its motion or due to its position; either kinetic or potential energy
🗑
|
||||
| electrical energy | Energy of electric charges or electric current
🗑
|
||||
| pulley | a simple machine that can change the direction of force
🗑
|
||||
| lever | a simple machine made with a bar free to move about a fixed point called a fulcrum
🗑
|
||||
| velocity | speed and direction of a moving body; average velocity can be calculated by dividing displacement by time
🗑
|
||||
| distance | the entire path an object travels
🗑
|
||||
| gravity | force of attraction between all objects in the universe
🗑
|
||||
| inertia | an object's tendancy to remain at rest or keep moving with constant velocity
🗑
|
||||
| Newton's Laws | laws of motion first stated by Isaac Newton
🗑
|
||||
|
🗑

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.
