200
Collision where the objects collide and move away together after the collision
What is a perfectly inelastic collision
300
Acceleration
What is a change in velocity over time.
300
Acceleration in the x-direction of projectile motion
What is zero
300
An object remains at rest, or in uniform motion in a straight line, unless it is compelled to change by an externally imposed force
What is Newton's 1st Law
300
Power
What is the rate of doing work (P = W/t)
300
The impulse acting on an object produces a change in momentum of the object that is equal in both magnitude and direction to the impulse.
What is the Impulse-Momentum Principle
400
An example of constant acceleration in real life
What is gravity
400
Initial velocity or angle
What are things you can change to increase accuracy or range

Free Body Diagram
What is a representation of forces on an object using a dot as the object and arrows in the direction of motion as forces
400
Conservation of Energy
What is if no work is added or removed by forces doing work on a system then the total mechanical energy will not change (E = constant or KE1 + PE1 = KE2 + PE2)
400
Conservation of Momentum
What is the concept that states that the total momentum of the system is conserved if the net external force acting on the system is zero

500
Determines the range of an object
What is initial velocity
500
Inertia
What is the ability of an object to resist change in motion
