Question

hector runs into the room, and throws his books onto the floor, which make a sound noise. this is an example of

• kinetic energy transferring between objects
• kinetic energy transforming into sound energy
• kinetic energy transforming into thermal energy

franz is playing baseball in the house, even though his mother told him not to. he slides into first base, and gets a rug burn on his leg. the heat generated by franzs leg against the carpet is an example of

• kinetic energy transforming into sound energy
• kinetic energy transforming into thermal energy
• kinetic energy being transferred between objects

Explanation:

First Question (Hector's Action)

• When Hector throws books, the books have kinetic energy (due to motion). When they hit the floor and make noise, the kinetic energy of the books is converted (transformed) into sound energy. The first option is about transfer between objects, but here it's a transformation to sound. The third is about thermal, which isn't the case here.

Franz sliding (kinetic energy) against the carpet generates heat (thermal energy). So kinetic energy is transformed into thermal energy. The first option is sound (not heat), the third is transfer between objects, but this is a transformation to thermal.

Answer:

B. kinetic energy transforming into sound energy (assuming the options are labeled as A, B, C with A: kinetic energy transferring between objects, B: kinetic energy transforming into sound energy, C: kinetic energy transforming into thermal energy)
