Stephen dashes to the store 720 meters away in 68 seconds. This is Stephen's average velocity.
What is 10.59 m/s

This is what would happen to the acceleration of an object if its mass remained constant but the net force acting on it were tripled.
What is the acceleration would also triple.

Two cars are in a head-on collision. Car A is much more massive than Car B. In the collision the total momentum of the two cars does this (increases, decreases, remains constant).
What is remains constant?

Phillips sees an irritating student riding a bicycle. Mr Philips runs the student down and hits them with his car. This is the object that experiences the greatest acceleration in the collision (Philips's car, the student on the bicycle, or they are equal).
Who is the student on the bicycle?

This/these is/are the section/s of the graph where the object is experiencing BALANCED FORCES
What is region B?

A toy robot walks 5 meters in the negative direction then turns around and walks 4 meters in the positive direction.
These are the distance traveled and the displacement of the robot.
What is:
d = 9 m
Δx = -1m

This is the relationship between mass and acceleration, according to Newton's Second Law.
What is an inverse relationship?

A rollercoaster car with a mass of 100kg is traveling with a velocity of 30m/s. This is the momentum of the rollercoaster car.
What is 3,000 kgm/s?
200
An object's mass is increasing and its velocity is remaining constant. The object's momentum must be doing this.
What is increasing?
300
The slope of this graph tells you the speed and direction of the motion.
What is a position vs time graph!
300
The definition of this term is any change in velocity over a period of time.
What is acceleration?
300
The forces acting on an object are balanced. The object must be doing this.
What is maintaining a constant velocity.
300
Two cars are in a head-on collision. Car A is much more massive than Car B. In the collision, Car A's momentum has a change of +200 kgm/s. This is the change in momentum of Car B.
What is -250 kgm/s?
300
A football player kicks a football such that the football experiences 250N of force. This is the force experienced by the player's foot.
What is -250N
400
The region of the graph where the object is travelling FASTEST
What is between points C and D (t= 8-12 s)
400
An object is moving along a straight path. After 1 second the object has traveled a total distance of 1,000 meters. After 2 seconds the object has traveled a total distance of 2,000 meters. After 3 seconds the object has traveled a total distance of 3,000 meters. This is the acceleration of the object.
What is 0m/s/s

Draw the free body diagram and find the net force of the following:
A cart is being pushed to the left by Frank with 20N and to the left by Janine with 15N. Friction is working against them with 10 N of force.

A spring-loaded dart gun and the dart inside it are initially at rest. The mass of the dart gun is 1 kg and the mass of the dart is 0.1kg. When the dart is fired, the final momentum of the dart is +2 kgm/s. This is the final momentum of the dart gun.
What is -2kgm/s?

A ball is initially rolling with a velocity of 110 m/s. The ball experiences an acceleration of -10 m/s2 until it comes to rest. This is the time it takes for the ball to come to rest.
What is 11 seconds?

A frictionless cart is pushed to the right with a force of 15N, AND to the left with a force of 10N. If the acceleration of the cart is 1m/s2, this is the mass of the cart.
What is 5kg?
