|---|---|---|---|---|---|
| motion | The state in which one object's distances from another is changing
🗑
|
||||

🗑
|
||||
| instantaneous speed | The speed of an object at one instant time.
🗑
|
||||
| speed | The distance an object travels per unit of time
🗑
|
||||
| velocity | speed in a given direction
🗑
|
||||
| slope | The steepness of a line on a graph.
🗑
|
||||
| acceleration | The rate at which velocity changes
🗑
|
||||
| force | A push or pull exerted on an object
🗑
|
||||
| unbalanced force | Forces that produce a nonzero net force, which changes an objects motion
🗑
|
||||
| balanced force | Equal forces acting on an object in opposite directions, not changing the motion of the object
🗑
|
||||
| newton | A unti of measurement that equals the force required to accelerate one kilogram of mass at a meter per second per second. E=MC^2
🗑
|
||||
| net force | The overall force on an object when the individual forces acting on it are added together.
🗑
|
||||
| friction | The force that one surface exerts on another when the two surfaces are rubbed together.
🗑
|
||||
| static friction | Friction that acts on objects that are not moving
🗑
|
||||
| gravity | The force that PULLS objects toward each other
🗑
|
||||
| sliding friction | Friction that occurs when one solid surface slides over another
🗑
|
||||
| rolling friction | Friction that occurs when an object rolls over a surface
🗑
|
||||
| fluid friction | Friction that occurs as an object moves through a liquid
🗑
|
||||
| air resistance | The fluid friction experienced when objects fall through air
🗑
|
||||
| free fall | The motion of a falling object when the only force acting on it is gravity
🗑
|
||||
| terminal velocity | The greatest velocity a falling object can achieve
🗑
|
||||
| inertia | The tendency in an object to resist any change in its motion
🗑
|
||||
| momentum | the product of an objects mass and velocity
🗑
|
||||
| Law of Conservation of Momentum | The rule that in the absence of outside forces the total momentum of objects that interact does not change.
🗑
|
||||
| average speed | The overall rate of speed at which an object moves
🗑

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.
