1. Newton’s 3 Laws of Motion

2. Newton’s First Law – Inertia
An object at rest will stay at rest, and an object in motion will stay in motion, unless acted upon by an outside force

3. Newton’s First Law – Inertia
Law of Inertia (Law 1)
Break it Down
An object at rest will stay at rest,
and an object in motion will stay in motion,
unless acted upon by an outside force
If an object is at rest it will never move
If an object is in motion it will never stop moving
UNLESS – a force acts on it
Friction and air resistance slow things down
Push or pull make things move

How does this picture relate to the law of Inertia (Newton’s First law?)?

6. Newton’s Second Law – Force and Acceleration
The acceleration of an object depends on the object's mass and magnitude of the force acting on it (F=ma)

7. Newton’s Second Law – Force and Acceleration
Law of Force and Acceleration (Law 2)
Break it Down
The acceleration of an object
depends on the object's mass and
magnitude of the force acting on it
(F=ma)
Acceleration: speeds up, slows down, or changes direction
The greater the mass the less acceleration (vice versa)
The greater the force the greater the acceleration (vice versa)
Equation for Force and Acceleration

Hint: Heavy cars and light motor cycles!

10. Newton’s Third Law – Action and Reaction
For every action, there is an equal and opposite reaction

11. Newton’s Third Law – Action and Reaction
Law of Action and Reaction (Law 3)
Break it Down
For every action
There is an equal reaction
There is an opposite reaction
For every force
The reaction force will be the same Newtons of force (depending on mass and acceleration)
The reaction force will be in the opposite direction
