If the speed exceed the maximum speed limit for a car moving a level circular track it will skid and go out of track. explain why ?
Answers
Answer:
It will skid and get out of the track as there will be imbalance of forces and the vehicle will get out of the track tangentially.
Answer:
At higher speeds cars become more difficult to manoeuvre, a fact partly explained by Newton's First Law of Motion. This states that if the net force acting on an object is zero then the object will either remain at rest or continue to move in a straight line with no change in speed. This resistance of an object to changing its state of rest or motion is called inertia. It is inertia that will keep you moving when the car you are in comes to a sudden stop (unless you are restrained by a seatbelt).
To counteract inertia when navigating a bend in the road we need to apply a force—which we do by turning the steering wheel to change the direction of the tyres. This makes the car deviate from the straight line in which it is travelling and go round the bend. The force between the tyres and the road increases with increasing speed and with the sharpness of the turn (Force = mass × velocity squared, divided by the radius of the turn), increasing the likelihood of an uncontrolled skid. High speed also increases the potential for driver error caused by over- or under-steering (turning the steering wheel too far, thereby ‘cutting the corner’, or not far enough, so that the car hits the outside shoulder of the road)
