How does the mass of a bowling ball that has been rolled down the lane affect the kinetic energy?

• The kinetic energy does not depend on the mass of the bowling ball.

• The kinetic energy is increasing proportional to the mass of the bowling ball.

• The kinetic energy is decreasing proportional to the mass of the bowling ball.

• The kinetic energy is increasing proportional to the square of the mass of the bowling ball.

The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed 
• Energy cannot be created or destroyed, it can only transformed
• Energy can't be created, destroyed or transformed

According to the Law of Conservation of energy, the amount of energy before and after a reaction must be the same. Which statement below is true?

• The total amount of energy is conserved
• The total amount of energy is less after a reaction
• The total amount of energy is more after a reaction
