1. Momentum is always conserved when collisions occur. Momentum is defined as being a quantity of motion, and it is a product of mass and velocity. A small object travelling with a high velocity has great momentum ( Ex. A bullet ), and a massive object travelling with a low velocity has great momentum (Continue reading “ENERGY AND MOMENTUM: Conservation of Energy, Linear Momentum, and Angular Momentum During a Collision”

ENERGY AND MOMENTUM: Conservation of Linear and Angular Momentum ( Part 1 )
Q: A ( 1kg ) ball of clay moving with a velocity ( vbi ) collides and sticks to the end of a ( 120cm ) rod of uniform mass ( 2kg ). Assuming that the ball and rod are at rest upon a frictionless surface: ( a ) Where is the new center ofContinue reading “ENERGY AND MOMENTUM: Conservation of Linear and Angular Momentum ( Part 1 )”
FORCE AND ACCELERATION: Systems of Torque and the Center of Mass
Thus far, physicists have not developed a concise definition of what constitutes mass and “ free space “. As a consequence, an overly simplistic definition of mass, albeit imperfect, may be used with convenience in laboratory settings. Mass, simply put, occupies free space. Relatively simple analyses of forces acting upon massive objects can be madeContinue reading “FORCE AND ACCELERATION: Systems of Torque and the Center of Mass”
