Please find an example question $($from any source$)$ that requires the information in each $$Question$$ listed in that document. You$$ll then explain how to answer each question, showing all the work, and ultimately, answer the question.

Some questions might answer multiple $$Questions$$ in this document. While you can use the same question more than once, you will need to re$-$explain how the question answers that addresses $$Question

$1.$ Why is the acceleration of uniform circular motion directed toward the centre of a circle?$2.$ Using circular motion to approximate elliptical orbits, how can you describe the motion of planets, moons $($natural satellites$)$ and satellites $($artificial satellites$)$ using mathematical relationships$/$formula$($s$)?$

$3.$ How was Newton able to use Kepler$$s laws that described the motion of planets as elliptical orbits around the sun, to develop his law of universal gravitation?

$4.$ What is the relationship between the kinetic energy$($due to motion$),$ the potential energy $($stored$)$ and the total mechanical energy of an object in a closed $($isolated$)$ system?

$5.$ What is work?

$6.$ How does the mechanical energy change in a system that is not isolated?

$7.$ What is power and how does it relate to work?
