Energy Transfer vs. Energy Transformation

1
Energy Transfer vs. Energy Transformation

• Energy TRANSFER is the passing of energy from one
  object to another object.
• Energy TRANSFORMATION is the changing of energy
  from one form of energy to another form of
  energy.

Mass Vs Weight

• Is weight and mass the same???
• No, mass is referred to as the amount of matter
  in an object.
• But Weight is the gravitational force an object
  experiences due to its mass.

4
Power

• Power is the rate at which energy is transferred
  or transformed.
• So if I am carrying a suitcase while going
  upstairs which has more powerif I walk slowly
  or run up the stairs?
• Power Energy Transferred
• Time

Newtons 1st Law

• An object at rest will remain at rest unless
  acted on by an unbalanced force. An object in
  motion continues in motion with the same speed
  and in the same direction unless acted upon by an
  unbalanced force.

8
Newtons 2nd Law

• Acceleration is produced when a force acts on a
  mass. The greater the mass (of the object being
  accelerated) the greater the amount of force
  needed (to accelerate the object).

9
Newtons 3rd Law

• For every action there is an equal and opposite
  re-action.

Lets see if we understand!

The Law of Conservation of Energy

• Energy is never created or destroyed!
• The total amount of energy will always remain the
  same!

Lets create a foldable!

• Take all the terms we just went over and put one
  term on each page of your foldable then give me
  an example to help you try to remember what that
  term means.
• An example of Newtons 3rd law is a rocket as the
  gases push out of the end the rocket is lifted up
  into space.
