Fernando is using a spring and a dowel to send foam balls into the air. How does his device convert energy from one form to the other?

• the light in the spring is transformed to potential energy in the ball

• the heat in the spring is transformed to kinetic energy in the ball

• the kinetic energy of the spring is transformed to heat energy in the ball

• the potential energy in the spring is transformed to kinetic energy

Ryan bends a plastic ruler backward and then releases it to hit a button. Force from the ruler causes the button to slide across a table. Ryan bends the ruler back 4 centimeters (cm) for starting point one, 6 cm back for starting point two, and 8 cm back for starting point three. What are the most likely results of his experiment?

• Starting point one: 16 cm

  Starting point two: 16 cm

  Starting point three: 16 cm

• Starting point one: 16 cm

  Starting point two: 26 cm

  Starting point three: 36 cm

• Starting point one: 36 cm

  Starting point two: 26 cm

  Starting point three: 0 cm

• Starting point one: 36

  Starting point two: 26

  Starting point three: 16
