When a car travels around a circular track?
While a car travels around a circular track at constant speed its: Around a circular track velocity is changing because its direction is changing.
When a car travels around a circular track at a constant velocity it is accelerating?
The answer is centrifugal force.
Is it possible for a car to travel around a circular track at constant speed?
An object, for example, can be moving at a constant speed around a circular track, but its velocity must be constantly changing in order for the object to be constantly changing direction. The magnitude of the velocity does not change, but the direction does. Yes.
Is the net force on a car zero if it driving in a circle at a constant speed?
A) Force is in the same direction as acceleration (in this case, centripetal). E) Because the car is moving at a constant speed, so there is no a. We get the net force is zero.
How does centripetal force affect circular motion?
As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. Thus, the work done by the centripetal force in the case of uniform circular motion is 0 Joules.
Why is a force required to maintain circular motion?
It’s necessary to have a centripetal force to maintain a circular motion because if there is no resultant force acting on an object (that is all forces acting on the object add to zero), then the object travels with uniform motion in a straight line, or stays at rest.
When a car goes around the corner at 20 miles per hour Why do we say it accelerates?
The car is accelerating because it’s changing direction. When a car goes around a corner at 20 mph, why do we say it accelerates? When something changes position or moves.
What does it mean to race on a circular track?
Racing on a circular track means running on a circular path such that the starting point and the finishing point coincide with each other. Let two athletes U and V started running on a circular track of length L metres from a same starting point P. The speed of U is u m/s and that of V is v m/s. (Kindly take care of the units)
How to calculate the length of a circular track?

For example, let u = 8 m/s, v = 5 m/s and w = 10 m/s and length of the circular track = 400 m. Also U and V are moving in same direction while W is moving in opposite direction.
What does it mean to race on a linear track?
Racing on a linear track means running on a straight path such that the starting point and the finishing point don’t coincide with each other. Some general statements involved in such type of questions are as follows-
Which is the winning point in a race?
The track or the path on which a race takes place is called a racecourse. The point from where a race starts is called the starting point, and the winning point or the finishing point is the point where a race finishes. The concept of Races can be further divided into two sections –
