Question

When a running car stops suddenly, the passengers tends to lean forward because of
A) Gravitational force
B) Inertia of motion
C) Law of conservation of mass
D) Both B & C

Answer 1

B) Inertia of motion 
Inertia is a property of matter that causes it to resist changes. For example, a ball kept on a table tries to be at rest (inertia of rest), A car moving with constant speed tries to move with constant speed (inertia of motion), A accelerating train moving on rail tries move on rail (inertia of direction) etc.


Please mark my answer as the brainliest.

Answer 2

Correct Option is (B)

Due to inertia our body moves forward when car stops suddenly.

When car is moving, our body is also moving with car. But when it suddenly apply brakes, it's start to decrease is speed but our body still try to move ahead because of inertia.
