Understanding Newton's First Law of Motion

What does Newton's First Law of Motion state about an object at rest?

• It will start moving on its own.

• It will remain at rest unless acted upon by an external force.

• It will change direction.

• It will increase its speed.

Why does a parked car not move on its own?

• Because of gravity.

• Because of air resistance.

• Because of friction.

• Because of inertia.

What force causes a ball to stop when rolled on a smooth surface?

• Gravity

• Air resistance

• Friction

• Magnetism

How do seat belts help in a moving vehicle according to Newton's First Law?

• They increase the speed of the vehicle.

• They provide an external force to stop the passenger's motion.

• They reduce the weight of the passenger.

• They change the direction of the vehicle.

What happens to passengers in a car when it suddenly stops, if they are not wearing seat belts?

• They remain in their seats without moving.

• They continue moving forward at the same speed.

• They move backward.

• They stop immediately with the car.
