Newtons 1st and 2nd laws
The First Law of Motion
-
Inertia Depends on Mass
The greater the mass of an object is, the greater its inertia, and the greater the force required to change its motion.
Intro
Newton's first law of motion states that an object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force.
On Earth, gravity and friction are unbalanced forces that often change an object's motion.
The Second Law of Motion
-
Intro
According to Newton's second law of motion, acceleration depends on the object's mass and on the net force acting on the object.
