An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line unless acted on by an unbalanced force.
What is the 1st law of motion?
100
the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
What is terminal velocity
100
9.8 m/s/s
What is the velocity of all falling objects?
100
force and mass
Acceleration depends on both _____ and _____
200
A= F*A
What is the formula for acceleration?
200
All objects act in pairs
What is the main meaning of the 3rd law?
200
the motion of a body when only the force of gravity is acting on the body
What is free fall
200
the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity.
What is terminal velocity?
200
Acceleration
______ is the rate at which velocity changes over time.
300
^v = g*v
What is the formula for velocity
300
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is the 2nd law of motion?
300
the curved path an object follows when thrown, launched, or otherwise projected near the surface of the earth
What is projectile motion
300
the motion of a body when only the force of gravity is acting on the body.

400
no
do action and reaction forces act on the same object?
400
a quantity defined as the product of the mass and velocity of an object
What is momentum
400
the curved path that an object follows when thrown, launched, or otherwise projected near the surface of the earth.
What is projectile motion
400
reaction
Every action has a _______
500
Mass
What does the Letter M stand for in the equation f=m*a
500
f=m*a
what is the formula for the 2nd law
500
the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object
What is inertia
500
A quantity defined as the product of the mass and velocity of an object.
