|---|---|---|---|---|---|
| Force | a push or pull
🗑
|
||||
| Describe force: | By its strength and by the direction in which it acts
🗑
|
||||
| SI unit used to measure strength | newton
🗑
|
||||
| How can direction and strength of force be represented? | By an arrow (head tells direction) (length indicates strength)
🗑
|
||||
| Net force | the overall force on an object when all the individual forces acting on it are added together
🗑
|
||||
| What does net force determine? | whether an object moves and which direction it moves
🗑
|
||||
| How to find the net force when two forces act in the same direction? | add the strengths of the individual forces together
🗑
|
||||
| When two forces act in the same direction what does it do to the net force? | Produces a greater force
🗑
|
||||
| How do you find the net force when two forces act in opposite directions? | subtract the strengths
🗑
|
||||
| When two forces act in opposite directions what does it do to the net force? | produces a net force in the direction of the larger force
🗑
|
||||
| If the net force is zero will the objects motion change | no because the forces acting on the object are balanced
🗑
|
||||
| Unbalanced force | forces that produce a non zero net force(which changes an objects motion)
🗑
|
||||
| Balanced force | equal forces acting on an object in opposite directions
🗑
|
||||
| How do balanced forces acting on each other affect it's motion? | balanced forces cancel and do not change the objects motion
🗑

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.
