Activity 4: Newton's Law of Gravity: The force of gravity between any two objects of masses mi and m2, separated by a distance of r is given by Gmm 1. Calculate the average gravitational pull on Pluto (use r - semi-major axis). 2. Approximate Pluto's orbit to a circle (with radius semi-major axis) and determine Pluto's tangential speed using what you know about rotational motion. How does this value compare with the values you found...

Activity 3: Kepler's Second Law: Objects in elliptical orbits sweep oul equal areas in'equal times. This implies that the orbital speed of a planet around the sun is not uniform - it moves farthest away (known as APHELION). In this section we will calculate the difference in this fastest at the point closest to the sun (known as the PERIHELION) and slowest at the point speed using Pluto as an example. Pluto's orbit...
