Question | Answer |
---|---|
Distance is ___. | The total ground covered throughout the entire trip. |
Distance is calculated by ____. | Adding together all stops and legs of a trip. |
Displacement is ___. | How far you are from where you started WITH direction. |
Displacement is calculated by _____. | Final distance - starting distance WITH direction. |
IF you are calculating displacement, and two measurements are in the same direction (ie. 35 m W, 14 m W) you _____. | Add them together to get a total displacement of 49 m W. |
IF you are calculating displacement, and two measurements are in the opposite direction (ie. 35 m W, 14 m E) you _____. | Subtract them to get a total displacement of 21 m W. (W has the higher #, so it is the direction of your final displacement). |
Speed is ____. | How fast you are going. |
What is the difference in a scalar # and a vector #? | Scalar = JUST the #. Vector = # AND direction. |
Velocity is ____. | Your speed AND your direction traveled. |
What two vocabulary terms are VECTORS? | Displacement and Velocity |
Acceleration is ____. | The RATE of change in your velocity. (m/s2) |
Acceleration is calculated by using the formula ___. | (Final Velocity - Initial Velocity) / Time |
Speed is calculated using the formula ____. | S = Distance / Time |
Velocity is calculated using the formula ___. | Velocity = Displacement / Time |
