Newton's First Law
object in motion STAYS in motion.
object at rest STAYS at rest
until ACTED upon by an unbalanced force
Newton's Second Law
Force=mass x acceleration, more force causes more acceleration, more mass needs more force to accelerate
Newton's Third Law
For every action, there is an equal and opposite reaction
mass
the amount of matter in an object
inertia
tendency of an object to resist change in motion
speed
measurement of the distance an object travels in one unit of time
unbalanced force
type of force that can change an object in motion
velocity
speed in a given direction
acceleration
an increase or decrease in speed or change in direction
object in motion
when its distance from another object is changing
force
a push or pull
weight
the force gravity exerts on an object
Newton
unit used to measure force
balanced force
type of force that will not change and object in motion
net force
sum of all forces acting on an object
gravity
invisible force that pulls objects together, force that keeps us on earth
friction
force that one surface puts on another when they rub against each other
