OUTCOME
By the end of the lesson you will recognise and apply Newton's Law of universal gravitation and model the motion of satellites and planets using uniform circular motion.
Engage
Using Newton's Law of Universal Gravity and Cavendish's refinement into a mathematical relationship, we can determine the mass of the Earth
LEARNING TASKS
Explain
1. Describe Newton's universal gravity in words and a diagram
2. How did Cavendish determine a value for G?
Explore and Elaborate
1. Use the Universal Gravity relationship to determine gE
2. Determine the force of gravity between the Earth and the Moon
3. Use the Universal Gravity relationship to determine the distance between Mars and the Sun,
1.611 x 10^21 Newtons
