Astrophysics I Solution 8
... Figure 1: Energy per unit satellite mass as a function of radius for a satellite on circular orbit around the Earth. 3. Due to friction with the Earth’s atmosphere, the satellite will lose a small amount of energy and therefore slow down. This means that its velocity will decrease at first, causing ...

kinetic energy
... or work is stored when a force does work “against” a force such as the gravitational force or a Hooke’s Law (spring) force. Forces that store or hide energy are called conservative forces. ...

Motion, Forces, and Simple Machines
... States: An object at rest stays at rest unless an unbalanced force acts on it. *An object moving in a straight line at constant speed will continue doing that unless acted on by a force. This force is called friction. It is a force that resists motion between 2 surfaces that are in contact. It alway ...

Newton`s Laws
... An English Mathematician and Physicist that formulated the three laws of motion, law of universal gravitation and invented calculus before the age of 30 Newton’s discoveries helped to answer many questions such as: what causes tides, how do the planets move and why do objects of different masses fal ...

Conservation of Mechanical Energy
... Conservative and non-conservative forces: Non-conservative forces: oWork does depend on path. oA force is non-conservative if it causes a change in mechanical energy (mechanical energy is the sum of kinetic and potential energy). oThis energy cannot be converted back into other forms of energy (irr ...

Physics Problem Checklist
... This is a checklist for solving mechanics problems involving moving objects with mechanical energy and momentum and possibly under the influences of forces. It will not be useful for more simple kinematics problems, where you are told something about an objects motion (position, velocity, accelerati ...
