Newtons Laws of Motion

​

Laws of Motion

• A scientist named Isaac Newton came up with three Laws of Motion to describe how things move scientifically.

  
  

  
  

Newton’s First Law of Motion:

• An object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on it.

• ​Inertia - An object that stays in motion​

Multiple Choice

An automobile you are riding in suddenly stops, but you continue to go forward.

• Newton's
  1st
  Law of Motion
• Newton's
  2nd
  Law of Motion
• Newton's
  3rd
  Law of Motion

Multiple Choice

What Newtons law does this picture represent

• Newtons 2nd law 
• Law of gravity 
• Newtons 1st law
• Newtons 5th law

Multiple Choice

When a cannon fires a cannonball we observe Newton's third law. Which force is the reaction force?

• The cannon moving forward
• The cannonball moving forward
• The cannon moving backward
• The cannonball moving backward

Newtons 2nd Law of Motion

• The second law states that the greater the mass of an object, the more force it will take to accelerate the object

• Force = mass x acceleration or F=ma.

  
  

• This means that the harder you kick a ball the farther it will go.

  
  

  
  

Multiple Choice

• 1st
• 2nd
• 3rd

Multiple Choice

When you push a boat off from the dock, you are demonstrating Newton's 3rd Law of Motion. It simply states that for every action there is an equal and opposite _______________?

• Motion
• Change
• Reaction
• Push

Newtons 3rd Law of Motion

• The third law states that for every action, there is an equal and opposite reaction.

  
  

• This means that there are always two forces that are the same

  
  

  
  

• In the example where you kicked the ball there is the force of your foot on the ball, but there is also the same amount of force that the ball puts on your foot.
