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.
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 power…if I walk slowly or run up the stairs? • Power = Energy Transferred Time
Newton’s 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.
Newton’s 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).
Newton’s 3rd Law • For every action there is an equal and opposite re-action.
Lets see if we understand! • http://teachertech.rice.edu/Participants/louviere/Newton/laws.html
The Law of Conservation of Energy • Energy is never created or destroyed! • The total amount of energy will always remain the same!
Let’s 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 Newton’s 3rd law is a rocket as the gases push out of the end the rocket is lifted up into space.
