www.tc.columbia.eduENERGY (or heat energy) is the energy of moving molecules. The energy that comes from a fire is thermal energy. MECHANICAL ENERGY is the energy stored in objects by tension. When the tension is released, motion occurs. A spring that is pressed down has mechanical energy. RADIANT ENERGY (or light energy) is related to the movement of light. The

www.nasa.govPotential energy (PE) is a stored form of energy that can produce motion, i.e. the “potential for motion.” Think of PE as stored energy that can become kinetic energy. You can calculate potential energy using an object’s mass and its height. PE is measured in Joules (J). PE = mgh where m = mass (kg), g = acceleration due to gravity

ocw.mit.edumeans that when r increases, the kinetic energy is transformed to potential energy such that, at infinity, the residual velocity is equal to zero. Hyperbolic Trajectory (e > 1) For a hyperbolic orbit, e > 1 and the semimajor axis a is negative. The energy is constant and given by 2 2 E = − 2 µ a = v 2 − µ r = v 2 ∞ (11)
Rotational Motion - Physics
physicscourses.colorado.eduConservation of energy problem with rolling motion: A sphere, a hoop, and a cylinder, each with mass M and radius R, all start from rest at the top of an inclined plane and roll down to the bottom. Which object reaches the bottom first? Apply Conservation of Energy to determine v final. Largest v final will be the winner.
