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)

Newton’s third law

For very action there is an equal and opposite reaction

Example for first

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

Example for second

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

Example for third

When your standing your pushing on the earth down in the earth with the same force it’s pushing on you
