Question

What happens to the kinetic energy of the baseball player due to the friction when she slides into second base?

It increases
It is destroyed
It's transformed into other forms of energy
It remains constant

Answer 1

When the baseball player slides into second base, the kinetic energy she has while sliding is affected by friction. The friction between her body (and the ground) works to slow her down, which means that some of her kinetic energy is converted into other forms of energy, primarily heat due to the frictional force. Therefore, the correct answer is:

**It’s transformed into other forms of energy.**
