|
laws by isaac newton that describes the relationship between motion and force
|
newtons laws of motion
|
|
|
an object at rest remains at rest and an object in motion maintains its velocity unless it experiences a net force
|
newtons first law
|
|
|
the tendency of an object to resist a change in motion unless an outside force acts on the object
|
inertia
|
|
|
the unbalanced force acting on an object equals the objects mass times its acceleration
|
newtons second law
|
|
|
a measure of the gravitational force exerted on an object
|
weight
|
|
|
gravitational force increases as mass increases,
it decreases as the distance increases |
law of universal gravitation
|
|
|
the motion of a body when only the force of gravity is acting
on the body |
free fall
|
|
|
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
|
terminal velocity
|
|
|
the curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth
|
projectile velocity
|
|
|
the force of your weight; ex) acts on ball
|
action force
|
|
|
a force that exerts a force on another object
|
action force
|
|
|
a force that acts in the opposite direction to an action force
|
reaction force
|
|
|
for every action, there is an equal and opposite reaction
|
newtons third law
|
|
|
a quantity defined as the product of the mass and velocity of an object
|
momentum
|
|
|
the total amount of momentum in an isolated system is conserved
|
law of conservation of momentum
|
