Question

A man standing on a bus remains still when the bus is at rest. When the bus moves forward and then slows down the man continues moving forward at the original speed. This is an example of the effect of

A. weight.
B. inertia.
C. velocity.
D. gravity.

Answer 1

When the bus starts moving forward, the man remains at rest,
causing him to lean back.

When the bus slows down, the man continues to move forward,
and appears to lean forward.

Both events are examples of the effect of inertia.
