Simple dynamics problem using energy methods
Here we solve for the velocity of a block as it's sliding up a circular hill using energy methods 1) Find work done by external forces (it's 0). 2) Notice there is negligible rotation so the kinetic energy is just 0.5 m (v2^2 - v1^2). 3)...

Is energy always conserved?
When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?

Introductory Kinetic Friction on an Incline Problem
You place a book on a 14° incline and then let go of the book. If the book takes 2.05 seconds to travel 0.78 meters, what is the coefficient of kinetic friction between the book and the incline?

Resultant Forces
A force is a push or a pull that acts on an object. Forces are vector quantities because they have both magnitude and direction, and so can be represented by an arrow. Scalar quantities have only magnitude and no direction. When several...

proof forces parallel to members in simple truss
Ever wondered why we neglect shear forces and bending moments in simple truss's? Here is a formal proof to show why we only consider axial forces (forces parallel to the members of the truss). It can only be done under three assumptions....
