Term 2 Week 1 2018

Homework

• Ex 4J, p. 143-147 Energy, Work, Power

Energy

Energy can never be created

Energy can never be destroyed

Energy can only change its form (Work is done)

Energy has the ability to make something happen, i.e. to do Work

The unit for energy is the Joule (J)

J = Kgm²s-²  in fundamental units

Term 1 Week 6 2018

Homework:

• Ex 4B Forces, p. 94-104
• Ex 4H Circular Motion, p. 132-134

Circular Motion

• Velocity is always at a tangent to the circle. Even if the speed remains constant, the velocity is changing because it is accelerating.

vc = 2𝝿r/T

• Centrapetal Acceleration is always toward the centre of the circle.
• ac = mv2/r
• Centapetal Force is the Net Force, and is also always towards the centre of the circle.

Fc = mv2/r
