7 flashcards · Physics · by Logan Pollack

1. Acceleration

   The change in velocity per unit of time

2. An object is accelerating if it is:

   speeding up, slowing down, or turning

3. Positive acceleration

   speeding up in the positive direction slowing down in the negative direction

4. Negative acceleration

   slowing down in the positive direction speeding up in the negative direction

5. the slope of a displacement/distance vs. time graph indicates

   speed/velocity

6. objects in free-fall

   objects in free-fall are acting only under the influence of the acceleration due to gravity

7. does mass affect objects in free-fall?

   no
