the speed and direction of an object
velocity
the movement of an object
motion
how fast an object is moving
speed
an object in motion stays in motion until acted upon by an outside unbalanced force, and an object at rest will stay at rest until acted upon by an outside unbalanced force
newtons first law
speeding up, slowing down, or changing direction
acceleration
the relationship between an object's mass, m its acceleration, a and the applied force, F is F = ma
newtons second law
for every action there is an equal and opposite reaction
newtons third law
the amount of matter in an object
mass
the tendency in an object to resist change in motion
inertia
the speed of an object in one instant of time
instantaneous speed
total difference traveled divided by the total amount of time taken to travel the distance
average speed
two or more forces acting on an object who's effects cancel each other out
balanced forces
a push or pull
force
an opposite force that acts on two objects touching
friction
SI unit for length
meter
how hard it is to stop an object
momentum
a combination of all forces acting on an object
net force
the amount of change in a measurement in a given amount of time
rate
two forces exerted on an object who's effects do not cancel each other out, therefore accelerating the object
unbalanced forces
SI unit for mass
kilogram
