|---|---|
 slope | the steepness of a line on a graph-tells you how fast one variable changes in relation to the other. what is this? |
| Force | is a push or a pull-changes the motion of an object |
| Force | mass*acceleration= |
| acceleration | the rate at which velocity changes |
| kilograms kg | mass is measured in |
| decreasing speed | when an object decelerates or slows down |
| turning a corner | an object is changing direction when it is |
| acceleration | final speed-initial speed/time is |
| straight line | constant speed |
| no speed (0) | horizontal line |
| slope | rise/run= |
| movement away from the reference point | upward line |
| fast movement | steep line |
| momentum | related to an object's mass and velocity |
| kg*m/s | momentum is measured in |
| indicate a direction | momentum includes velocity so you MUST |
| momentum | mass*velocity makes |
| speed | velocity is like |
| conservation of momentum | the total momentum before and after a collision of any group of objects remains the same, unless an outside force acts on the object |
| distance changes | speed is the rate at which |
| speed changes | acceleration is the rate at which |
| Newtons N | Force is measured in |
| kilograms kg | mass is measured in |
| m/s squared | acceleration is measured in |
| acceleration | Force/mass= |
| Force | mass*acceleration= |
| mass | Force/acceleration= |
