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/s2

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

18.   distance traveled divided by time traveled
