Question

A young boy is shown swinging over the water. Identify at least two types of friction that will have an effect on his speed. In your explanation, be sure to include the objects and motions that create friction.

Answer 1

If an object swings hanging from a string, the string bends with the movement and the deformation of the string dissipates energy, and this process can be regarded as one type of friction.

On the other hand, since the object swings submerged in a fluid (in this case, air), the movement of the object across the fluid creates air drag, which is another type of friction that will have an effect on the motion.
