Final answer:
When a physics student pulls back lightly on the right handlebar of a motorcycle, it causes the cycle to tip to the left and produce a left turn. This happens due to the principles of physics related to angular momentum and weight transfer.
Step-by-step explanation:
When a physics student pulls back lightly on the right handlebar of a motorcycle, it causes the cycle to tip to the left and produce a left turn. This happens due to the principles of physics related to angular momentum and weight transfer.
As the student pulls back on the right handlebar, it creates a gyroscopic effect because the wheels of the motorcycle have angular momentum. This gyroscopic effect causes the motorcycle to lean to the left, resulting in a left turn.
In addition, when the motorcycle leans to the left, there is a transfer of weight from the right side to the left side. This weight transfer helps the motorcycle to maintain balance while turning left.
