Energia Cinética

The kinetic energy of a body is the one that it possesses due to its movement. Equivalent to half the mass times velocity squared. The bottom block has twice mass and therefore twice as much energy than the above; the bottom block moves twice speed than the above then it has four times the kinetic […]

Energy of Tossed and Bounced Ball

Hi. This week’s lab is on exploring the mechanical energy of a volleyball as it gets tossed or bounced. Of course, you know something about the conservation of energy, where the kinetic energy as you throw something up changes into gravitational potential energy and changes back to kinetic on the way down so then you […]

Deriving the Work-Energy Theorem using Calculus

– Good morning. Today we are going to use calculus to derive the work-energy theorem. And I do understand because this is an algebra-based class that many of you have not taken calculus yet. However, I consider it important to sometimes see math which is a little bit more advanced than what you currently understand. […]

What Is Energy?

We need energy for pretty much everything, from keeping our bodies moving to keeping the sun burning. But where does it come from? And /why/ do we need it? What /is/ energy, anyway? Hey there! My name’s Alie Energy is pretty complicated, but we’re going to figure it out together! Physicists often describe energy as […]
