## Do all objects in motion, stay in motion?

In 1686, Sir Isaac Newton published the Laws of Motion, including the 1st Law of Motion: "an object in motion stays in motion unless acted upon by an outside force." This is often called the Law of Inertia.

## Evidence: Roller Skating Crash

This roller skater is evidence of Newton's First Law of Motion because the skater continues to roll (object in motion) until he runs into the sheep (an outside force).

## Do you need more force to accelerate an object with greater mass?

In 1686, Sir Isaac Newton published his Laws of Motion, stating that objects with greater mass require more force to accelerate them.

## Evidence: Pushing a Car

This picture is evidence of Newton's 2nd law of motion because it shows that it requires more force to push the van which weighs 2,000 kg than the car weighing 2,000 kg.

## For every action, is there an equal and opposite reaction?

In 1686, Sir Isaac Newton published his Laws of Motion. His 3rd Law of Motion stated that for every action, there is an equal and opposite reaction.

## Evidence: Newton's 3rd Law of Motion

This picture is evidence of Newton's 3rd Law of Motion because it shows that as the shoe pushed onto the grass, the grass also pushes back onto the shoe.

## Other Contributing Scientists

The law of inertia was first formulated by Galileo Galilei. Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest.

René Descartes provided the first form of the laws of nature and a conservation principle of motion.
