WebEnergy is transferred to an object by work when an external force displaces or deforms the object. The quantity of energy transferred is the vector dot product of the force and the displacement of the object. As forces are applied to the system they are distributed internally to its component parts. WebThe equations are most accurate for relatively heavy impacting masses moving at low velocities on impact. Notation A = Area (m 2) E = Modulus of Elasticity (N/m 2) h = Drop distance (m) k =Stiffness (N/m) M = Mass-moving body (kg) M 1 = Mass of static bar or beam (kg) K = Factor to allow for energy loss at impact l = length of bar (l)

"WebVideo transcript. Let's learn a little bit about springs. So let's say I have a spring. Let me draw the ground so that we know what's going on with the spring. So let me see, this is the floor. That's the floor, and I have a spring. It's along the floor. I'll use a thicker one, just to show it's a spring. " - Energy stiffness measure
