Simple Harmonic Motion and Elastic Energy
... In mechanical systems, energy can be stored in springs. For example a compressed spring on a popgun can provide energy to a pellet and shoot it from the gun. Even a simple slingshot uses the elastic energy stored in a rubber band to shoot it projectile. When two balls collide it is as if a spring is ...

Lesson #8: The Link Between Force and Motion
... Newton's second law of motion predicts the behavior of objects when all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables o the net force acting upon the object, and o the mass of the object. As the force acting upon an obj ...
