Kinematics

$200
The slope of a position-versus-time graph gives this quantity.
What is velocity?
$400
The area under a velocity-versus-time graph gives this quantity.
What is displacement?
$600
A ball dropped from rest falls for 3 seconds, and taking g as 10 meters per second squared, it falls this far.
What is 45 meters?
$800
On level ground with no air resistance, launching a projectile at this angle gives the greatest range.
What is 45 degrees?
$1,000
At the top of its flight a projectile has zero vertical velocity, but its acceleration is still this.
What is g, directed downward?

Newton's Laws

$200
Newton's first law is often called the law of this.
What is inertia?
$400
A net force of 20 newtons on a 4-kilogram mass produces this acceleration.
What is 5 meters per second squared?
$600
This force from a surface acts perpendicular to the surface on an object resting against it.
What is the normal force?
$800
A 10 kg box sits in an elevator accelerating upward at 2 meters per second squared, and with g as 10, the floor pushes up with this force.
What is 120 newtons?
$1,000
A 10 N push on a 2 kg block shoves it into a 3 kg block across a frictionless floor, and the blocks push on each other with this force.
What is 6 newtons?

Circular Motion and Gravity

$200
An orbiting astronaut feels weightless not because gravity vanishes but because she and her craft are in continuous this.
What is free fall?
$400
Doubling the distance between two masses changes the gravitational force between them by this factor.
What is one-fourth?
$600
A 2 kg ball moves at 3 meters per second in a circle of radius 1.5 meters, requiring this net force.
What is 12 newtons?
$800
A planet with twice Earth's mass and twice its radius has surface gravity this fraction of Earth's.
What is one-half?
$1,000
For a car rounding a flat, unbanked curve, this force supplies the centripetal force.
What is static friction?

Work and Energy

$200
This SI unit measures both work and energy.
What is the joule?
$400
A 2 kg object moving at 5 meters per second has this much kinetic energy.
What is 25 joules?
$600
Taking g as 10, lifting a 2 kg mass straight up 4 meters raises its gravitational potential energy by this much.
What is 80 joules?
$800
The rate at which work is done is this quantity, measured in watts.
What is power?
$1,000
A spring with a spring constant of 200 N/m compressed by 0.1 meters stores this much elastic potential energy.
What is 1 joule?

Momentum and Collisions

$200
Force multiplied by the time over which it acts, equal to the change in momentum, is called this.
What is impulse?
$400
In this type of collision, total kinetic energy is conserved.
What is an elastic collision?
$600
A 1 kg cart at 4 m/s collides with an identical cart at rest, and they stick together and move at this speed.
What is 2 meters per second?
$800
The total momentum of a system is conserved when this equals zero.
What is the net external force?
$1,000
An airbag reduces the force on a passenger by increasing this quantity during the collision.
What is the stopping time?

Rotation and Oscillation

$200
This rotational equivalent of force is found by multiplying a force by its lever arm.
What is torque?
$400
This rotational analog of mass depends on how an object's mass is distributed around the axis.
What is rotational inertia?
$600
A spinning skater who pulls in her arms speeds up because this quantity is conserved.
What is angular momentum?
$800
Making a simple pendulum four times as long multiplies its period by this factor.
What is 2?
$1,000
The period of a mass on a spring depends on the mass and this property of the spring, but not on the amplitude.
What is the spring constant?

Final Jeopardy — Going in Circles

For an object moving in a circle at constant speed, the net force on it always points in this direction.

What is toward the center of the circle?

How to run this board

This board covers the algebra-based mechanics at the heart of AP Physics 1: kinematics, Newton's laws, circular motion and gravitation, work and energy, momentum and collisions, and rotational motion and simple harmonic motion.

Many clues are conceptual rather than numerical, which matches the exam. When a team answers, ask them to justify it in one sentence using a physical principle - that is exactly the reasoning the free-response questions grade.

Give teams whiteboards for the calculation clues and a 30-second work window before the buzzers open, so the fastest reader does not always win.
