Dynamics: Force and Acceleration on a Rigid Body



Force and Acceleration

From force and acceleration of a particle we know that we can determine the force on a particle from Newton's second law F=ma. This is also true for rigid bodies. However, there is one additional aspect that needs to be considered for rigid bodies, which is rotation about a fixed axis. To determine the force from a body rotating around a fixed axis equation 1 would be used.

Rotational Force Equation (1)

α = angular acceleration

I = Mass moment of inertia

F = Force
