Motion and Force Study Guide answers.

1. Velocity- 30mph East

Speed – 30 mph

Distance – 30 miles or 30 ft or 30 kilometers

Time – 30 seconds, 30h (hours), or 30 min (minutes

Mass – 30 g (grams), 30 kg (kilograms)

Displacement – 30 ft North, 30 miles East, or 20 meters West

Force – 30 N (Newtons)

2. Greater, inertia

3. Friction

4. Speed – the distance traveled divided by the time traveled

Force – a push or pull

Displacement – distance and direction from a starting point to an ending point

5. Force

6. Put sand on an icy driveway, put wood under a tire stuck in the mud

7. Gravity

8. Inertia

9. Speed= distance/time

10. Velocity

11. m/s^{2}

12. its not moving

13. the speeding up, slowing down, or changing direction of an object

14. a car slowing down because of a stop sign

15. speed

16. motion

17. reference point
