Newtons Laws

• An object at rest will stay at rest. An object in
  motion stays in motion with the same speed and
  direction unless acted upon by an unbalanced
  force.
• The acceleration of an object is dependent upon
  two variables. The net force acting upon the
  object and the mass of the object.
• For every action there is an equal and opposite
  reaction.

Sir Isaac Newton

Newtons First Law
An object at rest will stay at rest. An object in
motion stays in motion with the same speed and
direction unless acted upon by an unbalanced
force.

Law application
Bob the Beaker hit a rock while moving on his
skateboard. He tumbled and broke. Which law of
physics applies to this situation?
Newtons 1st Law
Newtons 2nd Law
Newtons 3rd Law
15
Why Newtons 1st Law?

• Bob the beaker is traveling 10 miles an hour on
  his skateboard and being in motion, he wants to
  stay in motion. When his skateboard stops due to
  the rock, Bob still wants to carry on the motion
  and he falls.
• An object in motion stays in motion with the same
  speed and direction unless acted upon by
  an unbalanced force.

16
3rd Law application
During the 9th inning of the World Series, New
York Yankee Roger Clemens pitches the ball and
Atlanta Brave Kevin Millwood hits the ball out of
the park for a homerun. Which law of physics
applies to this situation?
Newtons 1st Law
Newtons 2nd Law
Newtons 3rd Law
17
Why Newtons 3rd Law?

• Clemmons baseball forces Millwoods bat to the
  right (an action) when they meet the bat forces
  the ball to the left (the reaction).
• For every action there is an equal and opposite
  reaction.

18
What happens when you blow up a balloon and then
let it go?

• The air moves out of the opening in one
  direction, (action) while the balloon
  moves in the opposite direction
  (reaction). The same is true of
  rockets. Rocket fuel ignites at the base of
  the rocket and the gases propel the rocket into
  space, in the opposite direction.

Balloon experiment

• Students are put into teams of 3.
• Each team gets 3 different sized balloons.
• The first balloon is inflated and launched on a
  line using a straw to fly on the line. They will
  repeat this with the other 2 balloons.
• Option for Advanced Students that successfully
  complete the first launches move on to a
  two-stage balloon rocket.
• Students record their findings and chart their
  distances on a worksheet.

Law Application

• create a journal entry answering which of
  Newtons laws applies to your balloon experiment,
  defend your answer. How did the shape or size of
  balloons affect the flight?

Further Exploration

• Making a Film Canister Rocket
• Create a cylinder and cone for the rocket shape,
  add fin shapes of your choice. Decorate!
• For propellant, place an
• Alka Seltzer tablet in the film
• canister and add water.
• and BLAST OFF!
• A modification to this lesson would be
• to use a stomp rocket instead.
