A particle of fixed mass m moving vertically in a constant (downward) gravitational field has vertical acceleration -g, where g is the strength of the gravitational field. The particle has: • Kinetic Energy K = mv2 • Potential Energy V = mgx. Here x is its height at time t and v = is its vertical velocity. Denote by E, the total energy, so E = K + . Show that E is constant.

A system consists of five particles. How many terms appear in the expression for the total gravitational potential energy of the system? (a) 4 (b) 5 (c) 10 (d) 20 (e) 25
Since the initial potential energy and final kinetic energy are zero, our equation now becomes EP,f = EK,i. We can then substitute the formula for kinetic energy, EK = 1/2mv2, and the formula for gravitational potential energy, EP = mgh, mghf = 1/2mvi2. Now it's just a matter of doing the algebra, solving for the final height hf, and substituting values to find hf. Notice that the mass m divides out of both sides of the equation, so the value of the mass is not needed to find the final height. Calculate the maximum height of the ball in meters. hf = __________ m
Consider the observation that the acceleration due to the gravitational force acting on a mass around a host planet decreases with the square of the separation between the objects. We can ask ourselves: why is it still accurate to consider a gravitational acceleration value of 9.8\frac{m}{s^2}9.8s2m for all of our projectile motion problems and all of our gravitational potential energy from prior modules? Let's analyze a situation and justify this analysis method: consider an object being launched from ground level to an altitude of 10,000 meters, roughly the cruising altitude of most jet liners, and far above our everyday experiences on Earth's surface. Compare the gravitational acceleration of the object at Earth's surface (the radius of Earth is about r_E=6.37\times10^6mrE=6.37×106m) to the acceleration value at the 10,000 meter altitude by determining the following ratio: g10,000m/gsurface
