If I hold a ball above the ground, it has potential energy. Once gravity pulls on it, it becomes kinetic. What is gravity and how does it convert one kind of energy to another?
That's a common misconception often asserted in textbooks and websites. Here is the correct way to see it.sayetsu said:If I hold a ball above the ground, it has potential energy.
Gravity converts potential energy to kinetic energy by pulling objects towards the Earth's surface, causing them to accelerate. As an object falls, its potential energy decreases and its kinetic energy increases.
Potential energy is the energy an object has due to its position or state. In relation to gravity, potential energy is the energy an object has due to its position in a gravitational field.
Kinetic energy is affected by gravity because it is the force of gravity that causes objects to accelerate and gain kinetic energy. The greater the force of gravity, the more potential energy an object has, and the faster it will accelerate and gain kinetic energy.
The formula for calculating the conversion of potential energy to kinetic energy is:
Kinetic Energy = Mass x Acceleration due to gravity x Height
Gravity affects the speed of an object as it falls by increasing its velocity as it falls towards the Earth's surface. As the object gets closer to the ground, the force of gravity becomes stronger and the object's speed increases.
