Potential Energy - Physics Classroom

Potential energy is one of several types of energy that an object can possess. While there are several sub-types of potential energy, we will focus on gravitational potential energy. Gravitational potential energy is the energy stored in an object due to its loion

Linear Momentum Questions with Solutions

The brakes in a car are used to stop the car hence to change the momentum of the car from some value to zero. The relationship between an applied force to an object of mass m and the change of its momentum in physics is given by F Δt = Δp = m (vf - vi) , vf final velocity and vi initial velocity, Δ t is the time during which force F is applied.

Ball Bearings: Guide to selection, appliions & calculations - …

X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r. P o = Axial load and is equal to P o = 0.6Fr + 0.5Fa. Where, F r is the radial force and F a is the Axial Force.
