Kinetic Energy, Mass and Velocity!
In this experiment, you can study the relationship between kinetic energy, mass, and velocity. The four buttons in the experiment are "rewind", "stop", "play", and "step". Time and the position of the mass is recorded automatically. Here are 3 questions to think about as you perform this experiment.- What happens when you increase the kinetic energy and keep the mass constant?
- What happens when you increase the mass and keep the kinetic energy constant?
- The relationship between kinetic energy, mass, and velocity is
Kinetic energy = 1/2 x mass x velocity x velocity
(K.E.=1/2 x m x v 2). Velocity is equal to distance/time. For a kinetic energy of 8 joules and a mass of 4 kilograms, at what time will the mass move 2 meters? Can you calculate it on paper before trying it in the experiment?
(If you don't have shockwave, here's what you would see if you did.)
