Projectile Motion
Relative Motion
100
This is the change in position of an object.
What is the displacement?
100
On a position-time graph, a straight horizontal line means the object is doing this.
What is staying at rest?
100
9.8 m/s2
What is the constant acceleration due to gravity on the Earth's surface?
100
The only force acting on a projectile after it is thrown.
What is gravity?
100
This is the standard assumed frame of reference.
What is the surface of the Earth?
200
This type of quantity has magnitude only, no direction.
What is a scalar?
200
On a velocity-time graph, the slope of the line represents this quantity.
What is acceleration?
200
At the peak of an object’s upward motion, this quantity is zero.
What is velocity?
200
The directions of velocity and acceleration at the top of a parabolic arc of an object thrown.
What are to the right and downward respectively?
200
You are standing on the ground watching a plane fly by. This is the frame of reference from which you'd consider the plane's velocity.
What is stationary frame of reference?
300
This is the derivative of position with respect to time gives this value.
What is velocity?
300
The area under the curve of a velocity-time graph.
What is the displacement between two points in time?
300
A ball is thrown straight up at 15 m/s. This is the time it takes to reach maximum height.
What is 1.5 seconds?
300
Along a perfect parabola with 5 evenly spaced points, these are the point(s) that have maximum speed.
What are the starting and ending points? (A and E)
300
From the frame of reference of a moving car, this is the direction a person standing on the sidewalk appears to be moving in which direction.
What is backwards?
400
This is the mathematical process used to determine an object’s displacement from a velocity-time graph.
What is integration?
400
An object has a position-time graph that curves upward, becoming steeper over time. This describes the motion.
What is speeding up with positive acceleration?
400
An object is dropped from a cliff and hits the ground in 3 seconds. This is the height of the cliff.
What is 45 meters?
400
This is the initial velocity in the x direction for a projectile launching off a cliff 40 meters high at 30 m/s in a 50 degree upward tilt.
What is 19.28 m/s?
400
2 people are facing forward inside a moving train; one is standing still and another is walking forward. A third person is standing outside the train car. To whom will a ball being thrown forwards inside the train appear to have the greatest velocity?
Who is the person standing outside the train?
500
An object’s velocity is given by v(t)=t^2-4t on the interval 0≤t≤5. This is the total distance the object travels during that time.
What is 13 meters?
500
This is a graph of acceleration-time. This is the direction of the net velocity. (0≤t≤5) 
What is negative?
500
A 2 kg object falls with a linear air resistance force of Fr=−4v. This is the terminal velocity it approaches.
What is 5m/s?
500
This is the final height of a rocketship with initial upward velocity 180 m/s.
What is 1620 m?
500
This is the path of a ball thrown vertically upward from a moving train as perceived by a stationary person watching from outside the train.
What is a parabolic path?
