Item EG002003: For two pinecones falling at the same speed, the pinecone with more mass has more motion energy.

Two pine cones are falling from a pine tree. Both pine cones are falling at the same speed.

If Pine Cone 1 weighs less than Pine Cone 2, which pine cone has more kinetic energy (motion energy)?

  1. Pine Cone 1 has more kinetic energy.
  2. Pine Cone 2 has more kinetic energy.
  3. Both pine cones have the same amount of kinetic energy.
  4. Neither pine cone has any kinetic energy.
