Final answer:
When approaching an object like an ambulance with your vehicle, you should stop and be stationary to ensure safety and comply with traffic laws. Experiencing sensations of being pushed outward while turning in a car is due to the centrifugal force, a result of the body's inertia in circular motion.
Step-by-step explanation:
When your vehicle moves closer to an object such as an ambulance, you must exercise caution and prepare to potentially stop moving and become stationary until it passes by.
This is important for safety reasons and to follow traffic laws. In situations involving emergency vehicles, it's vital to stop if you are in the path of the vehicle in order to allow it to pass quickly and unimpeded.
Understanding the concept of acceleration and motion can be witnessed when you are riding in a vehicle that turns a corner. If the steering wheel is held steady during the turn while maintaining a constant speed, you are experiencing uniform circular motion.
The sensation of sliding or being 'flung' outwards is due to what is known as centrifugal force, a fictitious force that results from your body's inertia, or tendency to continue moving in a straight line, as the car changes direction.
This effect is more pronounced the sharper the turn and the greater the speed of the vehicle.
