Final answer:
When a motorcyclist pulls back lightly on the right handlebar while driving at highway speed, it causes the motorcycle to tip to the left and produce a left turn. This happens due to the principle of angular momentum and the gyroscopic effect.
Step-by-step explanation:
When a motorcyclist pulls back lightly on the right handlebar while driving at highway speed, it causes the motorcycle to tip to the left and produce a left turn. This happens due to the principle of angular momentum and the gyroscopic effect.
When the motorcyclist applies a turning force by pulling back on the handlebar, it creates a torque that causes the front wheel to rotate to the left. As a result of this rotation, a gyroscopic effect is produced that causes the motorcycle to lean to the left, producing a left turn.
This phenomenon can be explained by the conservation of angular momentum. As the front wheel rotates to the left, it creates an opposing angular momentum that needs to be compensated. To achieve this balance, the motorcycle leans to the left, allowing the rider to safely make a left turn.
