Two-Dimensional Motion
... object in motion stays in motion, in a straight line, at a constant speed unless acted on by an outside force. 2nd Law…an outside force causes an object to accelerate…a= F/m THEREFORE, circular motion is caused by a force that causes an object to travel contrary to its inertial path ...

Elastic Potential Energy (Warning: Algebra required)
... 2. Draw a Force-Displacement graph for this motion and from this calculate the work done on the spring. Write this elastic potential energy in terms of the maximum force and the compression distance. 3. The mass is then released. Because the system is frictionless, energy is conserved. Draw a diagra ...
