Question

A mass connected to a light string oscillates in simple harmonic motion. The work done by air friction affects (Select all that apply)

A
the mechanical energy of the mass.
B
the kinetic energy of the mass.
C
the potential energy of the mass.
D
the thermal energy of the entire system.

Answer 1

Step-by-step explanation:

The work done by air friction affects:

B. The kinetic energy of the mass.

D. The thermal energy of the entire system.

Air friction dissipates energy from the system in the form of heat, which increases the thermal energy of the entire system. As a result, the kinetic energy of the mass, which is part of the mechanical energy, is also affected. The potential energy of the mass, however, remains unaffected by air friction as long as the oscillations are small and the potential energy is solely due to the mass's vertical position in a gravitational field.
