Principles of Physics in Driving Quiz

Objects tend to remain at rest or in uniform motion unless acted upon by an external force.

A heavier vehicle requires more force to stop, affecting its stopping distance.

Vehicle weight is a primary factor affecting fuel efficiency, as heavier vehicles require more energy to move.

Friction between tires and the road increases the grip, enhancing the vehicle's stability and handling.

Momentum quantifies the motion of a vehicle, being the product of its mass and velocity.

Rotational motion occurs when a vehicle turns around a curve.

ABS prevents skidding by maintaining traction between tires and the road, enhancing steering control during braking.

Rear spoilers utilize Bernoulli's principle to reduce air pressure above the car, increasing downforce for better traction.

Shock absorbers dampen vibrations from the road, maintaining stability and comfort.

The coefficient of friction determines the force necessary to prevent slipping between tires and the road.

Seat belts reduce the force of impact by spreading it over a larger area, thus reducing injury during a collision.

Newton's second law states that force is proportional to mass and acceleration, hence seat belts reduce the force experienced during a collision.

Newton's first law of motion explains that objects in motion tend to stay in motion unless acted upon by an external force, making it easier to turn the steering wheel when the car is in motion.

The law of inertia explains that an object in motion tends to stay in motion unless acted upon by an external force, hence turning the steering wheel changes the direction of the vehicle.

A lower center of mass provides better stability, reducing the likelihood of rollovers.

The law of conservation of energy explains that energy cannot be created or destroyed, so some of the vehicle's kinetic energy is converted to potential energy as it moves uphill, hence slowing down.
