Force

• Force is a push or a pull on an object.

Net Force

Net force is the total force on an

object.

Unbalanced ForceBalanced Force

• Unbalanced Force can cause an object to move, stop moving, or change direction.

•The balanced forces are the forces in equal and opposite directions.

•The balanced forces are the forces in equal and opposite directions.

Newton’s First LawNewton’s First Law

•An object at rest will stay at rest unless acted

upon by an outside force.

•Inertia is every objects resistance to change its

motion.

Inertia

Newton’s Second Law

• The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the object’s mass.

Force=mass x accelerationForce=mass x accelerationF=m x aF=m x a

• a = Force/ mass

• a = F/m

• a = Force/ mass

• a = F/m

Equation for Newton

•Newton=m x a.•Newton=m x a.

It’s the same as the force equation!
