2. What is the Kinetic enegy of an object?
a) formulae
b) of 1 Kg travelling 0.707 ms-1
c) 1000kg travelling at 3.6 kmph
2. When 100N is applied to a brick 0.5 kg over 1 m
a) what is the acceleration?
b) what is the work done on the brick?
c) what is the Kinetic Energy?
d) what is the final velocity?
e) comment on the formulae
v^2 = u^2 +2ad, where v is the final velocity, u is the inital velocity, a is the acceleration, and d is the distance.
About Me
- drhill
- I come from a Science family: My father Geoffrey Hill was Australia's first computer programmer on CSIRAC the fourth computer in the world. He is credited with invention of Computer music and the development of “Interprogram” a language before Basic. My PhD is in Atomic and Molecular Physics. I have researched the activated oxygen layer above the ozone layer, and 'Assigned' the world's smallest molecule. At the University of Toronto I researched high power UV lasers. I have specialized in automation in fibre optics. This developed into research in Machine Intellect and Robots. I have enjoyed work as an Explainer with Questacon and my time as a part-time soldier. I currently teach High School Science at Epping Boys’ High.
