Pre-test

a) Law of inertia b) F=MAc) Newton’s second law d) Two of these

Pre-test

Which law explains how rockets are launched into space?

a) For every action there is an equal and opposite re-action.

b) Law of inertiac) Law of universal gravitation d) F=MA

Pre-test

Everything moves in the universe and Newton’s laws describe why objects move.

Newton’s laws of motion are important to understand why things move. Anything from electrons in a neutron to why the planets move Newton’s laws can explain the movement.

We as people should have general understanding of Newton’s laws because we are always moving.

Anticipatory set:

The students should be able to explain and use Newton’s three laws of motion.

Intended Learning Outcome

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

This law is often called "the law of inertia".

Newton’s First Law

Newton’s First law

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

The Second Law gives us an exact relationship between force, mass, and acceleration.

FORCE = MASS times ACCELERATION.

Newton’s Second Law

Newton’s Second Law

For every action there is an equal and opposite re-action.

For every force there is a reaction force that is equal in size, but opposite in direction.

Newton’s Third Law
