This is the distance that a ball released from rest will fall during the 2nd second if it traveled distance H during the first second.
What is 3H?
200
This is the type of picture that can (should) be drawn for any dynamics problem.
What is a free-body diagram?
200
The force pulling an object toward the center of a circle while spinning.
What is centripetal force?

This is the name we give for the change in momentum.
What is impulse?

This mathematician's work on planar geometry, "Elements", is the foundation for most high school math geometry classes.
Who was Euclid?

This is horizontal acceleration at the top of a projectiles path.
What is 0 m/s/s?
300
This is the direction that kinetic friction acts on an object.
What is opposite of the motion?

I would grab the wrench further away from the rotational point (axis).
Where would you move your hand if you want to apply more torque to a wrench?

This is the final velocity a 500 kg car that starts at rest will have after it is rear-ended by a 650 kg that is initially going 20 m/s. The cars lock together after they hit.
What is 11.3 m/s?

Because gravity affects everything equally on Earth.
Why does mass not matter in kinematics?

This is the direction of the tension in a string when you twirl a ball in a circle above your head.
What is toward the center?

This is what must be true for an object to be in rotational equilibrium.
What is net torque equals zero?
400
One is where the masses combine, and one is where the masses bounce off each other.
What is the difference between an elastic collision and an inelastic collision?
400
This duo's works include "The Sound of Music", "South Pacific", and "Oklahoma!" just to name a few.
Who are Rodger's and Hammerstein?

This is the normal force on a 10 kg object that rests on an incline that makes a 25 degree angle with the horizontal.
What is 90.6 N?
500
If a box, ball, and thin hoop with the same size and mass are released down a frictionless ramp, THIS is the object that will reach the bottom first.
What is a three way tie?
500
By adding the momentum of the two objects either before or after the collision.
How do you find net momentum of a collision?
