LAWS OF MOTION

What happens to a moving object when two equal and opposite forces act on it?

Motion remains unaffected due to zero net force.

Why does a person fall when he jumps out from a moving train?

Inertia of motion causes the fall.

What causes a coin to drop into a tumbler when the card is flicked?

Inertia of rest allows the coin to fall.

Why does a ball thrown upwards in a moving train return to the thrower's hand?

Inertia of motion keeps it aligned with the train.

Why do people shake tree branches to get fruits?

Inertia of rest helps dislodge the fruits.

What is Newton's first law of motion?

A body remains at rest or in uniform motion unless acted upon by an external force.

Why does a passenger fall backwards when a train suddenly moves forward?

Inertia of rest causes the backward fall.

What happens to sliding doors when a corridor train suddenly starts?

Inertia of rest may cause them to open.

Why must one run after alighting from a moving bus?

Inertia of motion requires movement in the bus's direction.

What causes dust particles to be removed from a carpet by beating it?

Inertia of rest allows the dust to be dislodged.

Why is it advantageous to run before taking a long jump?

Inertia of motion aids in achieving distance.
