The axis of a graph where the DEPENDENT variable is found
What is the Y axis
100
When determining inertia, this physical property of an object is most important
What is mass.
100
The velocity of a car that travels 2000m in 100s
What is 20m/s
200
Newton's 1st Law
What is "An object at rest tends to stay at rest, and an object in motion tends to stay in motion unless an outside force is applied"
200
Difference between instantaneous and average velocity AND give an example.
What is "average is over a period of time; instantaneous is right at that moment in time; a spedometer gives the instantaneous velocity"
200
The time at which the car's distance equals 100km.
What is 8 seconds
200
An example of correct units when measuring velocity
What is "m/s or km/h...."
200
The acceleration of a plane that goes from 0m/s to 100m/s in 10s
What is 10m/s2
300
Law of Conservation of Momentum
What is "the total momentum before collision is equal to the total momentum after collision"
300
Difference between mass and weight
What is "mass is a property of matter; weight depends on gravity"
300
Time when does the train's velocity equal 10m/s
What is 5s and 13s
300
The symbol for "change" (such as a change in acceleration)?
What is "delta"
300
The momentum of a 15kg ball moving at 10m/s
What is 150kg*m/s
400
Newton's 2nd Law
What is "Force = mass x acceleration"
400
Why a box shoved across the floor eventually comes to a stop.
What is friction
400
The slope of the line on a distance vs. time graph for a bird that flies 1,000m in 250s
What is 4m/s
400
What happens to the momentum of an object that decreases its velocity
What is "its momentum decreases"
400
If a car is traveling at 100km/h, how far does it travel in 30 minutes?
What is 50km
500
An object that slows down (loses momentum) does NOT break the law of conservation of momentum BECAUSE:
What is "momentum lost by one object is gained by the other object"
500
A rollerblader throws a ball to his friend in front of him, and finds himself moving backwards. Why?
What is "an opposing reaction force"
500
From the graph of distance vs. time, draw the correct line on the speed vs. time graph.
What is "there should be a horizontal line at 5m/s, because that is the slope of the distance vs. time graph"
500
Convert 15m/s into km/h
What is 540km/h
500
A 10kg ball moving at 5m/s hits a stationary 2kg ball. The 10kg ball is stationary after the collision. What is the velocity of the 1kg ball after the collision?
