Motion
Question | Answer |
---|---|
Motion | When an object changes its position - dependent on the reference point. |
Reference Point | An indicator that orients you |
Distance | (d) how far an object has moved |
Displacement | Distance and direction of an object's change in position; difference from starting to ending point |
Speed | (s) the distance an object travels per unit of time |
Average Speed | Total distance traveled divided by total time traveled |
Instantaneous Speed | The speed at any given point - what shows up on your speedometer |
Velocity | (v) the speed of an object and the direction of its motion |
Velocity equation | v = d/t |
Slope | Steepness of a line (rise/run) |
Acceleration | Rate of change of velocity over time |
Positive Acceleration | When object speeds up |
Negative Acceleration | When object slows down |
Acceleration Equation | a = v(final) - v (initial)/ t |
Speed Equation | s = d/t |
