| The rate at which an object moves is its | speed
🗑
|
||||
| Change in position in a certain amount of time is | motion
🗑
|

| Circular motion is an example of constantly changing | velocity
🗑
|
||||
| Speed in a given direction is | velocity
🗑
|
||||
| A negative acceleration is called | deceleration
🗑
|
||||
| The velocity of an object changes if | either its speed or its direction changes
🗑
|
||||
| Even when slowly moving a train cannot stop suddenly because of its | large momentum
🗑
|
||||
| Speed that does not change is called | constant speed
🗑
|
||||
| The Law of Conservation of Momentum states that energy | cannot be lost or gained
🗑
|
||||

🗑
|
||||
| Newton’s Second Law of Motion relates to | force, mass, and acceleration
🗑
|
||||
| Newton’s Third Law of Motion describes | for every action there is an equal but opposite reaction
🗑

🗑
|
||||
| This is the energy of position. Energy that is ready to be used. | potential
🗑
|
||||
| Energy that exists for objects that are above the ground. Example: a rock on a cliff. | gravitational potential
🗑

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.
