|---|---|---|---|---|---|
| an objects change in position relative to a reference point | motion
🗑
|
||||
| an object that appears to stay in place | reference point
🗑
|
||||
| What are the reference directions? | North, South, East, West, Up, Down
🗑
|
||||
| What is an example of a common reference point? | Earth's Surface
🗑
|
||||
| the distance traveled divided by the time interval during which the motion occured | speed
🗑
|
||||
| What is resultant velocity? | When you add two velocities that are going the same direction
🗑
|
||||
| the speed of an object in a particular direction | velocity
🗑
|
||||
| If something is traveling in a straight line, it has a --- velocity. | constant
🗑
|
||||
| the rate at which velocity changes | acceleration
🗑
|
||||
| increase in velocity= ---- decrease in velocity= ---- | positive acceleration
negative accleration
🗑
|
||||
| the acceleration that occurs in a circular motion | centripal acceleration
🗑
|
||||
| a push or a pull exerted on an object in order to change the motion of an object | force
🗑
|
||||
| force has --- and --- | size and direction
🗑
|
||||
| Can force change acceleration? | yes
🗑
|
||||
| Can you see all forces? | no
🗑
|
||||
| the combonation of all of the forces acting on an object | net force
🗑
|
||||
| What does net force depend on? | direction
🗑
|
||||
| when forces on an object produce a net force of 0N | balanced
🗑
|
||||
| Will a balanced force change the motion of a moving object? | no
🗑
|
||||
| When the net force on an object is not 0N | unbalanced
🗑
|
||||
| Do unbalanced forces produce a change in motion? | yes
🗑
|
||||
| a force that opposes motion between two surfaces that are in contact | friction
🗑
|
||||
| Why does friction occur? | because the surface of object is rough
🗑
|
||||
| What does the amount of friction depend on? | the force pushing them together
🗑
|
||||
| If an object changes angle, does the amount of friction change? | no
🗑
|
||||
| friction between two moving surfaces | kinetic friction
🗑
|
||||
| what are the two types of kinetic friction? | sliding friction and rolling friction
🗑
|
||||
| When force is applied to an object but the object doesnt move | static friction
🗑
|
||||
| Give some examples of friction in real life | brakes on a bike, engine parts rubbing together
🗑
|
||||
| substances that are applied to a surface to reduce friction | lubricants
🗑
|
||||
| what is an example of a lubricant? | motor oil
🗑

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.
