A ball falls freely without air resistance. The main conversion is?
APotential to chemical energy
BPotential to kinetic energy
CKinetic to chemical energy
DKinetic to potential energy
Answer & Solution
Correct answer: B. Potential to kinetic energy
As the ball falls, gravitational potential energy decreases while kinetic energy increases.
