|---|---|---|---|---|---|
| Inertia | A body in motion tends to stay in motion; a body in rest tends to stay in rest
🗑
|
||||
| Newton's First Law of Motion | An object that is not subject to any outside forces moves at a constant velocity covering equal distances in equal times along a straight-line path
🗑
|
||||
| Vector quantity and magnitude | Consists of direction and magnitude; Magnitude is the exact quantity
🗑
|
||||
| Speed and velocity | Speed = distance/time; Velocity = how quickly one's position changes (speed with direction); usually in m/s
🗑
|
||||
| Forces | Outside influences that cause an object to move (mass x acceleration = kg*m/ sec^2 = Newton)
🗑
|
||||
| Acceleration | How quickly velocity changes (m/sec^2)
🗑
|
||||
| Inertial frame of reference | viewpoint of inertial object
🗑
|
||||
| Standard unit | Units that everyone agrees on, S.I.
(meters, meters/second, meters/second^2, Newtons, kilograms)
🗑
|
||||
| Newton | measurement of Force, mass x acceleration, kg*m/s^2
🗑
|
||||
| Grams | measurement of mass
🗑
|
||||
| Net force | Sum of all forces being exerted on an object
🗑
|
||||
| Newton's Second Law of Motion | The net force exerted on an object is equal to the product of that object's mass times the acceleration (Force = Mass x Acceleration) , the acceleration is in the same direction as the net force
🗑
|
||||
| Newton's Third Law of Motion | Every action has an equal and opposite reaction
🗑
|
||||
| Support forces | Forces that push each other along directly on a surface
🗑
|
||||
| Normal forces | Forces that are directed away from the surface (example, table exerts normal force on notebook)
🗑
|
||||
| Energy | The capacity to do work
🗑
|
||||
| Work | The process of transferring energy
🗑
|
||||
| Conserve quantity | Energy that cannot be created nor destroyed
🗑
|
||||
| Kinetic energy | Energy contained in object's motion
🗑
|
||||
| Potential energy | Energy contained between or within objects
🗑
|
||||
| Mechanical advantage | Process whereby mechanical device redistributes the amount of force and distance that go to performing a specific amount of mechanical work
🗑

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.
