What is the formula for energy transformation?
What is the formula for energy transformation? An object that has potential energy has energy by virtue of position and is related by the Newtonian equation PE=mgh (where m equals mass in Kg, g the acceleration due to gravity—approximately 9.8 m/s2 near Earth’s surface—and h equals height in meters). Is a potato a bulb? Potatoes […]
