---|---|---|---|---|---|
amount of ---- in an object | matter
🗑
|
||||
a push or pull | force
🗑
|
||||
when an object speeds up, slows, down. or turns | acceleration
🗑
|
||||
tendency of an object to resist a change in its motion | intertia
🗑
|
||||
a measure of how difficult it is to stop a moving object | momentum
🗑
|
||||
the SI metric unit of force and weight | newton
🗑
|
||||
represents force in science | arrows
🗑
|
||||
unequal force = movement + occurs | unbalanced force
🗑
|
||||
equal forces - no movement | force
🗑
|
||||
acceleration = (sf - si) time | acceleration formula
🗑
|
||||
What does acceleration change? | direction and speed
🗑
|
||||
What does momentum measure? | how hard it is to stop an object
🗑
|
||||
when your speed decreases Ex. when your speed changes from 10 mph to 6mph | negative acceleration
🗑
|
||||
Explain how mass and weight are affected when you travel to the moon? | Mass is constant and weight changes because there is less gravity on the moon
🗑
|
||||
a = sf + sli t | word problems - acceleration
🗑
|
||||
evidence of the pull of gravity between the moon and the earth (rise and fall of water) | tides
🗑
|
||||
a truck and a bicycle have the same momentum. which one would be harder to stop? | the truck because the mass and inertia are greater
🗑
|
||||
list 3 examples of forces that cannot be seen | magnetic, electric, gravity
🗑
|
||||
to have momentum what must an object be doing | moving
🗑
|
||||
3 ways to accelerate | speed up, slow down, change direction
🗑

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.
