What happens when the ball goes from left to right as it swings, slows down, and eventually stops?

• The amount of energy the ball has stays the same because it does not transfer any energy to the surroundings (air)

• Impossible to know without knowing the mass of the object

• GE and KE decrease because energy is transferred to the surroundings (air)

• The ball gains EE as it swings from left to right
