Newton's First Law
Motion can change though an action of a force
unbalanced forces
forces that result in a net force on an object and can cause changes in motion
inertia
the property of an object that resist changes in motion
the first law is often called the ____
law of inertia
an object accelerates when
forces are unbalanced
force causes
motion, acceleration, and change in motion
the amount of acceleration depends on force and ____
mass
1 newton is equal to
1 kg m/s2
larger force make a larger ____
acceleration
Newton's Second Law
a law of motion that states that acceleration is force divided by mass
formula for force
mass x acceleration
Newton's Third Law
a law of motion that states that for every action force there is a reaction force equal in strength and opposite in direction
when there is an action, there is always a ____
reaction
momentum
mass x velocity
Law of momentum
a law that states that as long as interacting objects are not influenced by outside forces, the total amount of momentum is constant
formula for momentum
p=mv
SI unit for mass
kg
SI unit for force and weight
Newton (N)
SI unit for momentum
kg m/s
