Question

question:
if a man is standing in a moving bus that then slows down, what causes the man’s body to continue moving at the original speed and hence push forward?

answer options:
select one of four
velocity inertia
gravity mass

Explanation:

The question is about the phenomenon where a man in a slowing bus continues moving forward. In physics (a subfield of Natural Science), inertia is the property of matter that causes an object to resist changes in its state of motion. When the bus slows down, the man's body, due to inertia, tends to keep moving at its original speed, leading to the forward push. Velocity is the speed with direction, gravity is the force of attraction between masses, and mass is the amount of matter in an object—none of these directly explain the tendency to maintain motion as inertia does.

Answer:

Inertia
