Motion Chapter review pg. 544 #1-30

1) Both are telling you how fast you are going.

2) Without acceleration you wouldn't be able to reach a certain speed of velocity.

3) Without velocity you wouldn't get to a steady momentum

4) Momentum is how hard it is to stop something using velocity and mass, and the las tests the total momentum of objects that collide.

5)Mass helps tell the outcome of how fast the momentum is going and how hard it will be to stop it.

6) Mass is a factor of inertia.

7) Momentum helps predict what inertia will do to an object

8) Average speed calculates all of seeds an object has traveled and instantaneous speed is an instants speed.

19)Your average speed would increase because the faster you run the same distance, your speed increases.

20)Between the acceleration of 0 and 3s, the speed has a steeper increase than between the 3 and 5 acceleration.

21)1m/s2

22)They bounce off each other.

23)30m west

24)You go backward and the ball goes forward.

25)It decreases speed as it goes up and increases speed as it comes back down.

26)The constant speed.

28)5m/s

29)1200km

30)a is going the fastest and c is going the slowest.
