newtons first law

Law of Inertia

newtons second law

f=ma

newtons third law

law of action and reaction

newtons first law definition

an object will remain at rest or at a constant speed unless it is acted upon by a force

newtons second law definition

the more mass something has the more force is required to accelerate it

newtons third law definition

when two objects interact, they apply forces to each other that are equal in magnitude and opposite in direction

Inertia

when an object resists a change in motion

the amount of inertia depends on ___

mass

more force=

more acceleration

less force=

less acceleration

large mass=

small acceleration

small mass

large acceleration
