Review

• You need to know the following vocab words
• Motion
• Reference Point
• Speed
• Velocity
• Acceleration
• Force

3
Balanced Forces

• Equal and opposite force on an object that
  results in NO change in motion or direction

4
Unbalanced Forces

• Unequal and opposite forces on an object results
  in a change of motion in the direction of the
  larger force

5
Newtons First Law

• An object in motion will stay in motion unless
  acted upon by an unbalanced force
• An object at rest will remain at rest unless it
  is acted upon by an unbalanced force

6
Newtons 2nd Law

• The net force on an object is equal to the mass
  of the object multiplied by its acceleration
• Force Mass x Acceleration
• The more force on an object, the more it will
  accelerate. The more mass an object has the more
  it will resist acceleration.
• Acceleration cannot occur without a force.

7
Newtons 3rd Law

• For every action there is an opposite and equal
  reaction.
• The same force acting on two different masses
  results in less acceleration of the larger mass
  than on the smaller mass.

8
Work

• When you exert a force on an object that causes
  it to move.
• Work Force x Distance

9
Potential Energy

• The energy stored in an object waiting to be
  released
• The higher an object is above ground the greater
  the potential energy

10
Kinetic Energy

• The energy of a moving object
• The amount an object has depends on the mass and
  velocity.
• Kinetic Energy Mass x Velocity2
• 2

Energy is transferred into kinetic energy as the
