| static friction | the force that occurs when 2 surfaces touch each other
🗑
|
||||
| kinetic friction | the force that occurs when 2 surfaces move against each other
🗑
|

| sliding friction | occurs when 2 objects rub against each other
🗑
|

| newton's 1st law of motion | (law of inertia) forces are unbalanced. ojects at rest tend to stay in motion, unlees acted on by an unbalanced force and objects in motion tend to stay in motion, at a constant velocity unlees acted on by an unbalanced force
🗑
|
||||
| newton's 2nd law of motion | (law of acceleration) forces are ____________; the net force on an object to the product of the mass and acceleration
🗑
|
||||
| newton's 3rd law of motion | (the law of interaction) "action-reaction" if 1 object exerts a force on another object, then the second object exerts a force of a equal strength in the opposite direction on the 1st object.
🗑
|
||||
| law of universal gravitation | ________ objects in the universe ________ each other, the size of the force created depends on the ________ of the object and the ________ between the objects
🗑
|
||||
| freefall | the motion of an object when ___________ is the only force acting on a object.
🗑
|
||||
| terminal velocity | greatest velocity of a particular falling object where the force of __________ is _____________ to the force of _____________________ on a particular object
🗑
|
||||
| weight | a measure of the force of gravity on an object
🗑
|
||||
| magnitude | the amount of something or the size of something; magnitude is never negitive
🗑
|
||||
| units of force | forces are measured in newtons (N)
🗑
|
||||
| law of conservation of momentum | the ________ momentum of any group of objects remains ________ unless outside forces (like gravity or friction) also act on the objects.
🗑
|
||||
| momentum formula | momentum= the product of an object's _______ and its ___________
(mass of object) x (velocity of object) p=mv
🗑
|
||||
| mass | the amount of matter in something
🗑
|
||||
| centripetal force | any force causes an object to move in a circle.
🗑
|
||||
| geosynchronous orbit | satellites orbit the earth at the same rate as earth rotates, therefore, a satellite is always above the same spot on the earth
🗑

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.
