newtons laws Flashcards
what is the definition of newtons 1st law?
an object at rest will stay at rest and an object in motion will stay in motion with the same velocity unless acted on by an unbalanced force.
what is the first law?
the law of inertia
what is an unbalanced force?
a net force on an object that can cause changes in motion.
what does inertia mean?
the property of an object that resists changes in its motion.
what does the net force means?
- multiple forces
- causes motion
- adding forces
what is newtons 2nd law?
acceleration is force divided by mass.
3 main ideas of newtons 2nd law?
- acceleration is the result of unbalanced forces.
- a larger force makes a proportionally larger acceleration
- acceleration is inversely proportional to mass.
what is the newtons 2nd law formula?
a= f

m
what is the definition of newtons 3rd law?
for every action force there is a reaction force equal in strength and opposite in direction.
what is the two third laws?
action and reaction
what does action and reaction mean?
action force- there is a reaction force equal in strength and opposite direction.
