Potential Energy Review with Force

A soccer player kicking a ball at 55 miles per hour uses more energy than a soccer player kicking a ball at 25 miles per hour. How do we know this is true? (Choose 2)

• Energy is energy

• There is a relationship between speed and energy

• Energy and speed are not related

• There is no way to know if this is true

• An object moving at a slower speed has less energy than the same object moving at a faster speed.

A student has a bowling ball and a basketball. The student rolled them both down a smooth floor.  Which object will require the most amount of force to get the ball to start rolling?

• The basketball because it has less mass

• The bowling ball because it has more mass

• The basket ball because it is larger

• There is no way to tell
