Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared (KE = 1/2 mv2).
Explanation:
When two sea caves on opposite sides of a headland are eroded and unite a sea arch forms.
Sea arch is a natural opening and a type of erosional landform that forms due to different rates of erosion, usually as a result of different resistance of bedrock.
