Question

As a train starts moving, a man sitting inside leans backwards because of

• A. inertia of motion
• B. inertia of rest
• C. conservation of mass
• D. momentum of inertia

Answer 1

Answer:

B. inertia of rest

• Inertia of rest is defined as the property of a body to resist any change in its state of rest.
• Ex: To remove the dust particles the mat is hit with the stick or against the wall.
• When the carpet is hit with a stick, the carpet moves, but the dust particles remain stationary due to the inertia of rest.
