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

1 - 200 If you travel 10m North then 20m South what is your distance? Displacement? Distance = 30m Displacement = 10m S

1 - 300 What is your displacement if you travel 5km North then 15km East? 15.8 km NE

1 - 400 If you travel 30km East then 60km West in 2 hours what is your speed? Velocity? Speed = 45km/h Velocity = 15km/h W

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

2 - 100 If a car is driving at 40km/h and slows down to 10km/h in 2 hours what is their acceleration? -15kg/h2

2 - 200 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

2 - 300 Draw a speed vs time graph of an object with constant acceleration

2 - 400 Draw a speed vs time graph of an object with no acceleration

2 - 500 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

3 - 100 What is the equation for momentum? P=mv

3 - 200 Inertia is dependent on what 2 factors? Mass and velocity

3 - 300 My bull weighs 20,000N what is his mass on earth? 2040.8kg

3 - 400 What is the gravity on Jupiter if an object’s mass is 25kg but it weighs 619.75N? 24.79m/s2

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

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

4 - 200 What is the net force of the diagram below? Fnet = 400 N down

4 - 300 What is the total amount of force acting on the box in the picture below? Total Force = 800N

4 - 400 What force would be required to accelerate a 50kg mass by 5m/s2? 250N

4 - 500 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

5 - 100 What law states that every action has an opposite and equal reaction? Newton’s 3rd Law

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

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

5 - 400 Newton’s 2nd law discusses the the relationship between what 3 factors? Force, mass and acceleration

5 - 500 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

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
