Where : GPE = gravitational potential energy (joules j) m = mass in kilogram (kg) g = acceleration due to gravity (m/s²) h = change in height h rather than the usual Δh (Note that h is positive when the final height is greater than the initial height, and vice versa), in meters (m) An object like a spring or a rubber band that has elastic properties can store elastic potential energy. To calculate Velocity: What you want to calculate. Acceleration(a) m/s 2. Potential energy is the amount of energy which an object has before it commences motion; in other words, it's the potential energy an object has or can be in. Answer (1 of 42): Well, if you don't have the velocity and/or mass, what other information do you have? Physics. It was introduced by Joseph-Louis Lagrange in 1788. For the pre-lab discussion, you can use the "Car and Ramp Lab" equipment and the "Timer and Photogate". This Airgun Energy Calculator is a simple widget designed to take the velocity of a projectile (bb, pellet, dart or bullet), its weight in grains, and calculate the foot pounds of energy (fpe) at the muzzle.
