1st Law of Motion

• Objects at rest will stay at rest and objects in
  motion will stay in motion in a straight line
  unless acted upon by an unbalanced force
• Inertia

7
2nd Law of Motion

• F m a
• An object accelerates in the direction the force
  is moving it
• Ex. Cannon is fired, ball propelled
• F (cannon) m (cannon) a (cannon)
• F (ball) m (ball) a (ball)
• m (cannon) a (cannon) m (ball) a (ball)

8
3rd Law of Motion

• For every action, there is always an opposite and
  equal reaction
• Ex. Fish fins

9
Gravity

• Gravity force that causes things to fall down
• two bodies will experience a mutual attractive
  force that is proportional to the product of
  their masses Encyclopedia of Earth and
  Physical Sciences

Other Achievements

• Written in Principia
• sound
• comets
• tides and equinoxes
• fluids

11
Activity

• Which of the laws of motion do you think are more
  important in our everyday lives? Explain.
• Reminder
• An object will stay in motion unless acted upon
  by an external force
• For each action, there will always be an equal
  and opposite reaction
