200

This physics principle allows you to relate the motion of objects before a collision or explosion to their motion after the collision or explosion.

What is the Conservation of Momentum?

200

During an inelastic collision, kinetic energy may be transformed into this.

What is sound, heat or light?

200
This is the rotational analog of mass for linear motion and roughly speaking it quantifies how hard it is to spin an object.
What is rotational inertia (or moment of inertia)?
200
The gravitational force changes by this much if you increase the distance between two planets by 3 times.
What is 1/9?
200

The force exerted on an object by a rope, string or chain.

What is a tension?

400

This physics principle allows you to calculate the normal force experienced by a 10 kg block on a horizontal surface that has a string pulling straight up on it with a tension of 48 N.

What is Newton's 2nd Law?

400
A frictionless roller coaster that starts at height 4h will be traveling this much faster than one that starts at height h.
What is twice?
400

When a spinning figure skater brings her limbs close to her body, this rotational quantity remains constant.

What is angular momentum?

400
A mass oscillating on a spring will have a zero acceleration at this point.
What is the equilibrium position?
400

The change in an object's momentum.

What is impulse?

600

The Voyager space probes will continue to move away from the Solar System at a constant velocity. This is best described by THIS physics principle.

What is Newton's First Law?

600
If the force and displacement do not have a component in this direction then no work is done.
What is parallel?
600

The equation that relates the net torque on an object with the rate that the objects angular velocity increases.

What is net torque = I * alpha?

600
The ratio of the force the Earth exerts on the moon to the force the moon exerts on the Earth.
What is one?
600

The tendency of an object to maintain its current state of motion.

What is the inertia?

800

Despite their differing masses, the Moon exerts a force on the Earth equal to the force that the Earth exerts on the Moon, as described by THIS physics principle. 

What is Newton's Third Law?

800

The total mechanical energy of a car-track-Earth system with negligible friction at the top of a hill is 500 J.  The total mechanical energy of the system half way down the hill is most nearly THIS.

What is 500 J?

800
The best angle (relative to the lever arm) to maximize the torque produced by a force.
What is 90 or 180 degrees?
800
Hooke's Law is defined by this relationship.
What is the force is directly proportional to the displacement? (F = kx)
800

Pushing on a door closer to the hinge than the handle produces less of this.

What is torque?

1000

This physics principle allows you to determine the net work done on an accelerating object.

What is the Work-Energy theorem?

1000

Kinetic energy is fully conserved during THIS interaction between two or more objects.

What is an elastic collision?

1000

You may treat an object as if all of its mass is acting at this position.

What is center of mass?

1000
A car driving at a constant speed around a circular track is experiencing this contact force directed toward the center of the track.

What is friction?

1000

An object that is not accelerating while falling through air with non-negligible air resistance is said to have reached THIS.

What is terminal velocity?
