Newtons Laws of Motion

Sir Isaac Newton

• Born Jan. 4, 1643 in England.
• As a young student he didnt do well in school.
• He worked hard and continued his education.
• Later in life he enjoyed learning and contributed
  ideas that became law to the science and math
  world.

Newtons First Law of Motion

• An object at rest tends to stay at rest and an
  object in motion tends to stay in motion with the
  same speed and in the same direction unless acted
  upon an outside force.

4
Newtons 2nd Law of Motion

• The acceleration (change of speed or direction)
  of an object depends on its mass and the amount
  of force applied.

5
Newtons Second Law of Motion
Force mass X acceleration
6
For example
Equal force on different masses will result in
different accelerations
7
Newtons Third Law of Motion

• "For every action, there is an equal and opposite
  reaction."
• Reaction
• Action

Fill in Notes Newtons Second Law

• F ma
• What does the equation mean?
• F Force (unit is Newtons)
• m mass (unit is Kilograms)
• a acceleration (unit is meters/second2)

9
Units

• Force is measured in Newtons
• Mass is measured in grams, kilograms etc.
• Acceleration - the rate at which an object
  changes its velocity." (remember speed with
  direction)
• Acceleration values are expressed in units of
  velocity/time. Typical acceleration units include
  the following
• m/s/s mi/hr/s km/hr/s

10

• Remember that velocity is the speed and direction
  of an object. And
• Remember that speed is the rate of change of an
  objects position. Well
• Acceleration is the rate of change of an objects
  velocity.

11

• Force is defined as a push or pull that one
  object exerts on another object.
• Mass is the amount of matter contained in an
  object.

12

• So what does this mean
• Newton found a connection with force, mass and
  acceleration.
• Force mass x acceleration
• You will need to use the Triangular Formula
  to solve for problems.
