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