100
What is the formula for speed?
Speed = Distance / Time
100
A vector has... (2 things)
Magnitude (how big) and direction (which way).
100
What is acceleration?
A change in velocity over time.
100
What is Newton's Second Law state?
Force = mass x acceleration
100
What does the line represent on a distance/time graph?
The slope represents the speed.
200
If a runner travels 100 meters in 20 seconds, what is their speed?
5 m/s
200
What is the net force on the object? In which direction?
0 N. The forces cancel out.
200
Acceleration happens when... (2 things)
A change in velocity or direction occurs.
200
What is the unit of force?
Newtons (N)
200
A straight, diagonal line on a distance–time graph shows what?
Constant speed.
300
A car travels at 60 km/hr. How far will it go in 2 hours?
120 km
300
What is the net force on the object? In what direction?
400 N down.
300
A bike goes from 4 m/s to 10 m/s in 3 seconds. What is the acceleration?
2 m/s2
300
What is the force on a 2 kg object accelerating at 3 m/s²?
6 N
300
What is happening in this graph? Describe its motion.
The object is moving with a constant speed and then stops moving at 5s.
400
A cyclist travels 750 meters at a speed of 5 m/s. How long does the trip take?
150 seconds
400
What is the net force on the object? In which direction?
2 N to the right.
400
A car speeds up from 10 m/s to 20 m/s in 5 seconds. What is its acceleration?
2 m/s2
400
A 10 kg object experiences a force of 50 N. What is the acceleration?
5 m/s2
400
What type of motion is depicted in this graph? Explain WHY. 
It shows acceleration because the speed is not constant.
500
A train travels 1,200 meters in 45 seconds. What is its speed in m/s and km/s?
26.7 m/s
0.26 km/s
500
What is the acceleration on the object? In which direction?
10 N Force / 5 kg =
2 m/s2
500
A roller coaster changes velocity from 15 m/s to 5 m/s in 2 seconds. What is its acceleration?
-5 m/s2
500
If mass doubles and force stays the same, what happens to acceleration?
It is cut in half.
500
What is happening in this graph? Describe the motion. 
The object is moving forward with a constant speed, it stops, then continues moving forward at a constant speed, and then returns to its original position.
