PHY250L Lab 6: Work & Conservation of Energy SPRING 2024

Pre-Lab Questions 1. In this lab, you will conduct three experiments that will demonstrate the concepts of work, potential energy and kinetic energy. Briefly explain those three concepts and their mathematical definitions. Work is when a force causes a mass to move. The unit that describes work called Joules or (J), the formula for work is (Work=F11d). F11 represents the force applied when it’s placed along (d), which represents displacement. When the force is moving with the movement then Work=fdcos(0) would be better. Also, this equation requires the magnitude and the angle coefficient. Potential energy is the stored energy associated with the position of an object. The formula for this is (PEgravity=mgh), m is the mass, (g) is the gravity and (h) is the height. Kinetic Energy is the energy associated with the state of motion in an object. The formula that represents kinetic energy is KE=1/2mv^2. (m) is the mass and (v)^2 is the velocity squared.
