The velocity of an object is the change in distance divided by this important physical quantity
What is time?
100
The most common unit used to express the energy in a system
What is the joule?
100
The acceleration of an object in the x-direction, and the acceleration of an object in the y-direction (both including proper units)
What is 0 m/s^2, and -9.81 m/s^2?

I am on the road observing a truck moving 50 miles an hour. I use a radar to check the speed of a baseball thrown on the truck. I find it to be going 130 miles/hour. It is going this fast in the frame of the truck.
What is 80 mph?

This nuclear process results in the heat and light produced by the sun
What is nuclear fusion?

You are given the initial and final velocity of an object that is dropped. This is the best motion equation to use if you want to find the time it took for that object to drop
What is Vf = Vi + at?
300
I shoot a beam of light ahead of me and find it to be moving at 3x10^8 meters/second. My friend who is driving by in his spaceship at 5000 meters/second sees the light moving at this speed
What is 3x10^8 m/s?
300
In a non-ideal world, the amount of potential energy a ball has before it is dropped is greater than the kinetic energy it will have after it touches the floor. This is because small amounts of these two types of energy are "lost" in this non-ideal world
What is sound energy and thermal energy?
300
The value of this variable in 2D motion problems is the same for equations in both the x- and y-direction
What is time?
400
This quantity is equal to acceleration x "Delta T".
What is "Delta V"?
400
Another way of representing one joule of energy, using only units of kilograms, meters, and seconds. Hint: consider the equation for kinetic energy.
What is 1 (kg* (m^2))/(s^2)?
400
An orange is thrown to the ground with an initial velocity of 2 m/s, and falls a distance of 5 meters. The equation Vf^2 = Vi^2 +2a∆x can be used to determine the final velocity of this orange just before it hits the ground. This is the value of this velocity
What is 10.1 m/s?
500
Karen's car is on fire (again) and I know that she is located at the coordinate (6,7) In my coordinate system. She is this distance away from the origin. ...answer in meters
What is the square root of 85 (~9.2) meters?
500
An object with a mass of 40 kilograms is dropped from a height of 10 meters. Half way down, the velocity of the object is measured to be this value
What is 9.9 m/s?
500
A ball is thrown up with a velocity of 5 m/s. Using the equation Vf = Vi + at, determine how much time the ball spends in the air. It takes the ball this many seconds in total to go up and then back down again
