| Question |
Answer |
| acceleration |
the rate of change in the speed of an object. |
| delta |
"the change in" |
| constant accleration |
speed that changes by the same amount every second |
| uniform accleration |
another word for constant acceleration |
| slope |
rise: amount the speed changes / run: amount the time changes |
| term |
piece of an equation |
| initial speed |
first term of the formula is the speed the object starts with |
| free fall |
moving under the influence of gravity only |
| acceleration due to gravity |
symbol: (g)equation: 9.8m/sec2 |
| time of flight |
object takes the same time going up as it takes coming down |
| friction |
when air resists the motion of objects moving through it |
| air resistance |
when small objects at low speeds is neglected by air |
| terminal speed |
maximum speed at which an object falls when limited by air friction |
| acceleration equation |
accelertaion= change in speed/ chang in time= meters per second/second=meters/ second X second=m/sec2 |
