At what speed can the cars round the curves without needing to rely on friction to provide a centripetal force?
If the car has a speed of about 11 m/s, it can negotiate the curve without any friction.
What provides the centripetal force for a car driving on a flat circular track?
friction
As a car makes a turn, the force of friction acting upon the turned wheels of the car provides centripetal force required for circular motion. As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion.
What provides the centripetal force needed to allow a car to turn a corner?
frictional force
Going Around Corners and Friction Without centripetal force, or a force towards the center of a circle, you would instead travel in a straight line. The centripetal force for a car going around a corner is provided by the frictional force.
What is the maximum speed at which a car can round a curve?
10 m/s.
Why does your body feel as if it is being pushed into the car door when going around a turn?
Explanation: What the person is actually feeling is a direct result of the 2nd part of Newton’s 1st Law, meaning that an object in motion will continue in that path unless acted upon by an external unbalanced force. So, when a person is traveling around a circle, their body wants to continue in a straight line.
Can centripetal acceleration change the speed?
The direction of motion is always tangential at point in a circular path. The acceleration, which is directed toward the center has no component along the direction of velocity. Therefore, centripetal acceleration cannot change the magnitude of velocity or speed of circular motion.
What can be the maximum speed of a car?
In April 2018, the Union Ministry of Road Transport and Highways fixed the maximum speed limit on expressways at 120 km/h, for national highways at 100 km/h, and for urban roads at 70 km/h for M1 category of vehicles. The M1 category includes most passenger vehicles that have less than 8 seats.
What is the maximum speed of a car taking a turn of radius 30 m on a level road?
The maximum speed of a car on a road–turn of radius 30 m, if the coefficient of friction between the tyres and the road is 0.4, will be. 6.84 m/sec.
What is a f’m known as?
A: The equation a=F/m or the acceleration is equal to the net force of an object divided by that object’s mass, is an equation derived and explained by Sir Issac Newton’s second law of motion. Newton’s second law of motion states that the force of an object is equal to the mass times the acceleration of that object.
Is it possible for a car to move in a circular path in such a way that it has a tangential acceleration but no centripetal acceleration?
An object is kept in circular motion by a centripetal force that is always directed to the center of the circle. Therefore, it is not possible for a car to move in a circular path in such a way that it has a tangential acceleration but no centripetal acceleration.
