Question

a car driving down the road suddenly slams on the breaks and comes to a screeching stop. pick the statement that best describes the energy transfer that takes place.
mechanical energy was transferred into potential energy in the form of gas and oil and some energy was transferred into nuclear energy
kinetic energy was transferred into mechanical energy and thermal energy while some was destroyed into the black void of space.
potential energy was transferred into kinetic energy between the brakes and fiction with the road and some energy transferred into chemical energy
mechanical energy was transferred into some thermal energy between the brakes and friction with the road and some energy transferred into sound energy

Explanation:

Step1: Analyze energy conservation

Energy cannot be created or destroyed, only transferred or transformed.

Step2: Consider car - braking scenario

When a car brakes, its kinetic energy (due to motion) is involved.

Step3: Evaluate energy transformations

Kinetic energy is transformed. Friction between brakes and road causes heating (thermal energy) and sound (sound energy).

Answer:

Mechanical energy was transferred into some thermal energy between the brakes and friction with the road and some energy transferred into sound energy.
