Chapter Four
measurement and motion
| Question | Answer |
|---|---|
| acceleration | the rate of change of velocity over time |
| uniform acceleration | see constant accelertaion |
| air resistance | the resisting effect on a moving object due to friction of air. |
| delta | the symbol that indicates the difference or change between two quantities. |
| slope | a line's vertical change divides by its horizontal change |
| time of flight | the elapsed time an object or projectile spends in the air |
| m/sec^2 | a metric unit of measure for velocity |
| free fall | movement that is due only to the force of gravity. |
| friction | the force that opposed the relative motion of bodies. |
| initial speed | the speed an object has at the beginning of an experiment |
| term | a component of an equation |
| terminal speed | maxium speed reached by an object in free fall; the speed at which forces of gravity and air resistance are equal |
| constant acceleration | an accerelation that does not change; it is due to a velocity that changes at a constant rate |
| acceleration due to gravity(g) | the acceleration of anobject due to earth's gravitational field strength;equal to 9.8 m/sec^2 on earth |
