Newton's first law states that objects in motion stay in motion and objects at rest stay at rest unless acted upon by an external force. Newton's second law establishes that the force on an object is equal to its mass times its acceleration. Newton's third law specifies that for every action force there is an equal and opposite reaction force. The document provides examples of applying Newton's second law to calculate an unknown force and assigns a project to draw Newton's three laws of motion on a poster.

1. Newton’s First Law
What is Newton’s 1st law??
• Objects in motion stay in motion
• Objects at rest stay at rest

2. Newton’s Second Law
Force is equal to an object’s mass times its acceleration

f ma
m = 1000 kg
a = 0.05
f = ???
f = 50 N

3. Newton’s Third Law
All forces exist in pairs (pair = 2)
For every action, there is an equal and opposite reaction
THERE CANNOT BE ONE FORCE

4. Project
Draw a picture of Newton’s 3 laws on poster board.
Due end of class on Monday.
