Newton’s First and Second Laws

Mrs. Wharton’s Science Class

Newton’s 1st Law of MotionStates that an object at rest will stay at rest,

and an object in motion will stay in motion unless acted on by an outside, unbalanced force.

Also called the law of inertia

InertiaAn object’s resistance to change in motionAmount of inertia an object has depends on

it’s mass. The greater the mass the greater the inertia

Newton’s 2nd Law of MotionStates that acceleration depends on an

objects mass and the net force acting on an object.

Acceleration= net force/ mass

AccelerationAcceleration increases if force increases.Acceleration will increase if mass decreases
