Question

four students are doing different friction experiments with a cylinder. tristan is working with static friction, arya is working with sliding friction, anoush is working with rolling friction, and keran is working with fluid friction. which most likely describes results from their experiments? tristan and arya would exert more energy to overcome friction than anoush and keran. tristan and anoush would exert more energy to overcome friction than arya and keran. tristan and keran would exert less energy to overcome friction than arya and anoush. tristan and arya would exert less energy to overcome friction than anoush and keran.

Explanation:

Static friction (Tristan) is the force needed to start moving an object, and sliding friction (Arya) is the force to keep a sliding object moving; both are significantly stronger than rolling friction (Anoush) and fluid friction (Keran). Rolling friction is much lower than sliding friction, and fluid friction (resistance from a fluid) is the weakest of the four. This means more energy is required to overcome static and sliding friction compared to rolling and fluid friction.

Answer:

Tristan and Arya would exert more energy to overcome friction than Anoush and Keran.
