Gravitational kinetic energy is the energy an object possesses due to its motion within a gravitational field. This energy is dependent on the mass and velocity of the object.
The formula for gravitational kinetic energy is KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.
Gravitational potential energy is the energy an object has due to its position in a gravitational field. When an object falls, it converts this potential energy into kinetic energy. As the object falls, its potential energy decreases and its kinetic energy increases.
No, gravitational kinetic energy cannot be negative. Since both mass and velocity are squared in the formula, the resulting value will always be positive.
The law of conservation of energy states that energy cannot be created or destroyed, but can only be converted from one form to another. Gravitational kinetic energy is one form of energy that can be converted into other forms, such as potential energy or thermal energy.
