|---|---|---|---|---|---|
| speed equation | distance divided by time
🗑
|
||||
| speed | the rate at which an object moves
🗑
|
||||
| motion | a change in postion in a certain amount of time
🗑
|
||||
| average speed | speed that changes over time
🗑
|
||||
| constant speed | speed that does not change over time
🗑
|
||||
| velocity | speed in a given direction
🗑
|
||||
| acceleration | rate of change in velocity
🗑
|
||||
| deceleration | a decrease in velocity
🗑
|
||||
| momentum | depends on the mass of the object and the velocity with which it is traveling
🗑
|
||||
| acceleration equation | (final velocity-orginal velocity)divided by time
🗑
|
||||
| momentum | mass x velocity
🗑
|
||||
| average speed | final distance divided by final time
🗑
|
||||
| Types of Friction | Rolling, Fluid, Sliding
🗑
|
||||
| Rolling Friction | Produced by such objects such as wheels or ball bearings. Tends to be less than sliding friction.
🗑
|
||||
| Sliding Friction | When solid objects slide over each other
🗑
|
||||
| Balanced Force | force acting on an object that will NOT change the object's motion
🗑
|
||||
| Unbalanced Force | force that acts on an object that will change its direction
🗑
|
||||
| Force | A force gives energy to an object, sometimes causing it to start moving, stop mofing or change direction. A push or a pull
🗑
|
||||
| Friction | A force that acts in a direction opposite to the motion of the moving object. Friction will cause a moving object to slow down or stop.
🗑
|
||||
| Fluid Friction | Occurs when objects move accross or through fluids or gases
🗑
|
||||
| Sir Isaac Newton | Laws of motion
🗑
|
||||
| 1st law | Inertia - an object a rest remains at rest and an object in motion remains in motion unless acted upon by an unbalanced force.
🗑
|
||||
| 2nd Law | Force = mass x acceleration (the larger the force the larger the acceleration)
🗑
|
||||
| 3rd Law | Every action has an equal and opposite reaction.
🗑

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.
