This is the equation for the force of gravity down an inclined plane
What is mgsin(theta)
An object moving in a circle at a constant speed experiences force acting in this direction
A kart is rolling on a frictionless surface in the rain. As it rains, the kart begins to fill up with a significant amount of water. As this happens, this happens to the velocity
What is it decreases?
An object is launched with a vertical velocity of 900 m/s and an horizontal velocity of 2 m/s
This is its velocity in the x direction at the peak of it's arc
What is 2 m/s?
This is the equation for the magnitude of the force of friction of an object sliding down an inclined plane at a constant speed, written in terms of m, g, theta, and mu
What is mu*m*g*cos(theta)

Bronny James jumps from the free throw line to dunk. He dunks the ball 1.4 seconds after leaving the ground. This is his hangtime
What is 2.8 seconds?
Noel and Taryn stand on a perfectly frictionless sheet of ice that continues infinitely in all directions
Taryn pushes Noel with a force of 10 N
This is how far Noel travels
What is... Noel travels for an infinite distance, unless he is acted on by an outside force.
This is the centripetal force acting on a penny with a mass of 1g, being swung on a path with a radius of 1m at a speed of 4m/s
What is 16N
Blue light from a far away galaxy travels a great distance. During that time, the universe continuously expands. This makes the light from that distant galaxy appear (to an observer on Earth) to appear more this color.
What is red?
