newtons laws

Newton’s first law

An object in motion stays in motion, unless an external force acts upon it

Newton’s second law

When a force acts on an object, it will cause the object to accelerate(f=ma)

Newtons third law

For every action, there is an equal and opposite reaction

Example for newtons first law

A ball sitting on a table isn’t going to move unless a force acts upon it

Example for newtons second law

If a ball is rolled up a hill, the force of gravity acts upon it in the opposite direction of motion a.k.a. negative acceleration

Example for newtons third law

When you’re standing, you’re pushing down on the earth with the same force, it’s pushing on you
