100
This is a car's speed if it moves 20 km in 10 minutes.
What is 2 km/min?
100
This is a push or a pull.
What is a force?
100
This law is called the law of inertia.
What is Newton's First Law?
100
This kind of force has a "net force" of zero.
What is a balanced force?
100
On a distance-time graph, a horizontal line means this.
What is no movement or stopping?
200
This is the velocity of a person that walked 200 meters east in 4 minutes.
What is 50 m/min east?
200
When an object changes speed or direction.
What is acceleration?
200
You sit on a chair and are not moving. Your force on the char and the force pushing back from the chair describes this law.
What is Newton's Third Law?
200
This type of force acts against the force of an object's motion.
What is friction? (or an unbalanced force)
200
The slope of a distance-time graph shows this.
What is speed?
300
This is the amount of force applied to a 10 kg mass that gets it to accelerate to 2 m/s2.
What is 2 Newtons?
300
This term describes the combined forces acting on an object.
What is the net force?
300
Objects with more mass will have more of this, because they are harder to move.
What is inertia?
300
This force would cause a ball to stop rolling on the ground.
What is friction?
300
In an experiment to determine whether the mass of an object affects its speed, this would be the independent variable.
What is the mass?
400
This is the distance that an object would travel if it is moving 10 m/s for 5 seconds.
What is 50 meters?
400
This term describes when an object's distance from another changes.
What is motion?
400
This is how a 1-kg object object could have the same force as a 100-kg.
What is if it had a very large acceleration?
400
This is an example of a force that can act at a distance to another object.
What is gravity or magnetism?
400
This is how you would calculate the total stopping distance of a car.
What is the reaction distance plus the braking distance.
500
This is a jogger's average speed over 300 meters if he jogs for 5 minutes, stops for 5 minutes, then jogs for another 10 minutes.
What is 15 m/s?
500
This term describes an object that is moving, but its speed does not change.
What is a constant speed?
500
An unbalanced force causes an object to do this (whether it is moving or not).
What is accelerate?
500
A horse pulls a cart to the east with 150 Newtons. Friction acts with a force of 50 Newtons. What is the size and direction of the net force?
What is 100 Newtons east.
500
The slope of a speed-time graph would show this.
What is acceleration?
