Question | Answer |
---|---|
Acceleration | Is the rate of change in the speed of an object. |
free fall | an object is in free fall if it is moving under the influence of gravity. |
accceleration due to gravity | the acceleration of 9.8 m/sec^2 is important it is given its own name and symbol |
time of flight | if a problem asks for the time of flight remember that an object takes the same time goiing up as it takes coming down. |
air resistance | air resistance is so small it may be neglected |
terminal speed | the maximum speed at which an object falls when limited by air friction |
slope | slope of a graph is equal to the ratio of rise to run |
delta | translates to the change in |
constant acceleration | has the same speed that changes by the same amount every sec |
uniform acceleration | motion with constant acceleration appears as a sloped straight line on a speed versus time graph |
term | a piece of an equation |
initial speed | the first term of the formula is the speed the object starts with |
