Why couldn't the ball harm Tom's face according to the principle demonstrated?

• Because the ball was lightweight

• Because of Tom's quick reflexes

• Due to the conservation of energy

• Because of the instructor's intervention

What was the instructor's precaution during the demonstration?

• Standing at a safe distance

• Using a soft ball

• Holding Tom's head

• Wearing safety goggles

What mistake did the instructor admit to making with the dinosaur?

• Choosing the wrong angle

• Not calculating the swing properly

• Using a heavier ball

• Pushing the ball as he let go

What is the key takeaway from the experiment?

• Energy transformation is unpredictable

• Energy can be created and destroyed

• Energy cannot be created or destroyed, only transformed

• Kinetic energy is more powerful than potential energy
