Newton's Laws of Motion

Categorize

Options (12)

inertia

Law of acceleration

action reaction

object in motion will stay in motion until an outside force acts on the object

the acceleration of an object is dependent on it's mass and the force applied

for every action there is an equal and opposite reaction

forces act in pairs

F=m x a

seatbelts stopping your body from flying forward

You throw a ball in outer space and it goes until something stops it
