What is the formula for calculating speed?

3 Speed = Distance / Time

4 What causes motion?

5 Unbalanced forces

6 Describe the motion as a result of these forces. 2 kg 8 kg A

7 An object will move to the left because there is more force pushing in that direction

8 How long will it take a car to travel 200 miles at 50 mph?

9 4 Hours

10 What is the difference between speed and velocity?

11 Direction

12 A push or a pull

13 A force

14 A force occurring between all objects in the universe. The mass and distance between these objects determines the strength of this force

15 Gravity

16 Force which resists motion

17 Friction

18 In which case is acceleration of the block greater? 1N→ 1 kilogram 4N → 1 kilogram

19 4N→ 1 kilogram

20 An object in motion stays in motion, and an object at rest will stay at rest unless acted upon by an outside force

21 Inertia

22 The two forces which affects the motion of a car down a ramp

23 Gravity and friction

24 What is the force that keeps sneakers from sliding around (resists motion)?

25 Friction

26 Frictional force increases when the mass of an object

27 increases

28 The dependent variable in the car ramp lab and in Pinball Wizard.

29 TIME

30 To increase reliability of experimental results, and increase confidence in results, scientists should…

31 Complete more trials and/or increase the sample

32 You travel to a city 200 km away in 2.5 hours. What is your average speed?

33 80 km/h

34 16 cm/n is an example of

35 velocity

36 A car travels for ½ an hour at a speed of 60km/h. How far does the car travel?

37 30 km

38 A plane traveling at 180 km/min comes to a stop in 10 minutes. What is its acceleration?

39 -18

40

41

42 Who’s average speed is faster?

43 Springer

44 Describe an object’s speed when speed does not change over time

45 Constant speed

46 Two variables plotted on motion graphs

47 Distance & Time

48 What Science Materials do you need to calculate speed?

49 Timer & Metric Ruler/Meter Stick

50 How far has the boat traveled?

51 60 km
