aw why? are you deleting the app for school?
gravity increases with height. gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground
At a roller coaster, energy conversions from potential to kinetic energy and back repeatedly several times across the course of a trip. Kinetic energy is the force that an object possesses as a consequence of its movement.
All moving objects possess kinetic energy, which is defined with the mass and speed of the object. Potential energy is the energy that is deposited in an object due to its position corresponding to some zero point. Gravitational potential energy is highest at the top of the looping point of a roller coaster and smallest at the deepest end.
