Final Jeopardy

2. 1 - 100 What is the difference between distance and displacement?
Direction

3.
If you travel 10m North then 20m South what is your distance? Displacement?
Distance = 30m
Displacement = 10m S

4.
What is your displacement if you travel 5km North then 15km East?
15.8 km NE

5.
If you travel 30km East then 60km West in 2 hours what is your speed? Velocity?
Speed = 45km/h
Velocity = 15km/h W

6. 1 - 500 What is the momentum of a 500kg cow running at 2m/s?
1000kg*m/s

7.
If a car is driving at 40km/h and slows down to 10km/h in 2 hours what is their acceleration?
-15kg/h2

8.
A dog is laying in the grass and then sees a squirrel, the dog accelerates at a rate of 1m/s2 and has a final velocity of 3m/s, how much time did it take the dog to reach this velocity?
3 seconds

9.
Draw a speed vs time graph of an object with constant acceleration

10.
Draw a speed vs time graph of an object with no acceleration

11.
A deer runs at a constant velocity of 4m/s, but then gets caught in headlights and immediately comes to a stop in 4 seconds. What is the deer’s acceleration?
-1m/s2

12.
What is the equation for momentum?
P=mv

13.
Inertia is dependent on what 2 factors?
Mass and velocity

14.
My bull weighs 20,000N what is his mass on earth?
2040.8kg

15.
What is the gravity on Jupiter if an object’s mass is 25kg but it weighs N?
24.79m/s2

16. 3 - 500 Why are the units for acceleration m/s2?
Velocity is distance (displacement) over time meters/seconds
Acceleration is velocity over time so multiple m/s by 1/second and you get meters/second2

17. 4 - 100 What happens to an object when unbalanced forces act on it?
The object will move

18.
What is the net force of the diagram below?
Fnet = 400 N down

19.
What is the total amount of force acting on the box in the picture below?
Total Force = 800N

20.
What force would be required to accelerate a 50kg mass by 5m/s2?
250N

21.
Calculate the acceleration of a 300,000kg jet just before take off if the thrust for each of its 6 engines is 40,000N.
.8m/s2

22.
What law states that every action has an opposite and equal reaction?
Newton’s 3rd Law

23. 5 - 200 F=ma, is the equation associated with which law?
Newton’s 2nd law

24. 5 - 300 What does Newton’s 1st law state?
Object at rest stays at rest, object in motion stays in motion unless acted upon by an outside force

25.
Newton’s 2nd law discusses the the relationship between what 3 factors?
Force, mass and acceleration

26.
If a pebble and a large rock are thrown with the same about of force, which will have a higher acceleration, why?
The pebble because it has a lower mass, therefore more force more acceleration

27. Final Jeopardy
Please sketch a graph of an object on BOTH a distance vs time and speed vs time graph if the object:
Going at a fast constant speed
Come to a stop
Then increases speed quickly
