Hooke`s Law Simple Harmonic Motion
... It is possible to compensate for the loss of energy in a damped system by applying an external sinusoidal force (with angular frequency ω) The amplitude of the motion remains constant if the energy input per cycle exactly equals the decrease in mechanical energy in each cycle that results from resis ...

Projectile Motion
... Many would insist that there is a horizontal force acting upon the ball since it has a horizontal motion. This is simply not the case. The horizontal motion of the ball is the result of its own inertia. When projected from the truck, the ball already possessed a horizontal motion, and thus will main ...

Momentum
... earlier unit, a vector quantity is a quantity which is fully described by both magnitude and direction. To fully describe the momentum of a 5-kg bowling ball moving westward at 2 m/s, you must include information about both the magnitude and the direction of the bowling ball. It is not enough to say ...

Chapter 4: Forces and Newton`s Laws of Motion
... The free body diagram (FBD) is a simplified representation of an object, and the forces acting on it. It is called free because the diagram will show the object without its surroundings; i.e. the body is “free” of its environment. We will consider only the forces acting on our object of interest. Th ...

... Since the individual angular momentum can change, the total angular momentum of the system can change. Both internal and external forces can provide torque to individual particles. However, the internal forces do not generate net torque due to Newton’s third law. Let’s consider a two particle system ...
