|---|---|---|---|---|---|
| You can increase acceleration by increasing this. | Force
🗑
|
||||
| What does Newton's 2nd Law state? | The acceleration of an object depends on the object's mass and the net force acting on it.
🗑
|
||||
| What are the two formulas for acceleratiion? | net force / mass and (final velocity - initial velocity) / change in time
🗑
|
||||
| What is the formula for force? | mass * acceleration
🗑
|
||||
| What are the units for force? | Newtons and kg * m/s^2
🗑
|
||||
| What does Newtown's 3rd law state? | For every action, there is an equal and opposite reaction.
🗑
|
||||
| What is the formula for momentum? | mass * velocity
🗑
|
||||
| What is the unit for momentum? | kg * m/s
🗑
|
||||
| Movement results from this type of force: | unbalanced
🗑
|
||||
| What is terminal velocity? | When an object reaches its greatest velocity while falling. When the force of air resistance = the weight of the object.
🗑
|
||||
| Formula for speed: | Distance / time
🗑
|
||||
| Formula for distance: | speed * time
🗑
|
||||
| Formula for time: | distance / speed
🗑
|
||||
| Three ways an object can accelerate: | speed up, slow down, change direction
🗑
|
||||
| What is a balanced force? | Opposing equal forces that cancel each other out.
🗑
|
||||
| What are the two ways to increase the acceleration of an object? | Increase force or decrease mass.
🗑
|
||||
| Why would an object have more inertia? (Newtown's 1st Law) | Because it has more mass, and the more mass an object has, the more inertia it has, and the harder it is to start and stop.
🗑

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.
