7-2 Conservation of Momentum
... Conservation of Momentum applies only in the absence of external forces! In the first two sample problems, we dealt with a frictionless surface. We couldn’t simply conserve momentum if friction had been present because, as the proof on the last slide shows, there would be another force (friction) i ...

... U ( x, y, z ) is a potential-energy function associated with a particle, then the force on the particle associated with that potential energy is given by F(x, y, z ) = −∇U (x, y, z ) , which is a vector field (a force field!). As an example, let's consider the gravitational force on a particle near ...

Energy Transformation on a Roller Coaster
... The motion of a pendulum is a classic example of mechanical energy conservation. A pendulum consists of a mass (known as a bob) attached by a string to a pivot point. As the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion. Neglecting air resistance (which wou ...

... Momentum Conservation in Collisions A Proof, using Newton’s Laws of Motion. If masses mA & mB collide, N’s 2nd Law (in terms of momentum) holds for each: ∑FA = (pA/t) & ∑FB = (pB/t). pA & pB, = momenta of mA & mB ∑FA & ∑FB = total forces on mA & mB, including both internal + external forces.
