Question

Rahul wants to change the motion map shown so that it shows uniform circular motion. An illustration of a circle with four black dots on the top, bottom, left and right of the circle. Each dot has a vector toward the center of the circle of equal length and a vector tangent to the circle in a counterclockwise direction and of increasing length staring from the one on the right. What change should Rahul make? He should change the length of each vector that points toward the center so that it is the same length as the vector pointing tangent to the circle at that point. He should change the lengths of the vectors that point tangent to the circle so that each is the same length. He should change the direction of the vectors that are tangent to the circle so that each points away from the center of the circle. He should change the direction of the vectors that are tangent to the circle so that each points toward the center of the circle.

Answer 1

Rahul should change the lengths of the vectors that point tangent to the circle so that each is the same length.

Uniform Circular Motion:

A uniform circular motion is a motion in a circle where the tangential speed of the object is constant.

In the motion map:

• The arrows pointing towards the center of the circle represent the centripetal acceleration, and their length represents the magnitude of the acceleration.

• The arrows pointing tangentially to the circle represent the tangential speed, and their length represents the magnitude of the speed.

In this motion map,  the length of the vectors pointing tangent to the circle is not constant: this means that the speed is not constant. In order to have a uniform circular motion, the speed must be constant, therefore the lengths of the vectors that point tangent to the circle must be the same.

Thus, we can conclude that Rahul should change the lengths of the vectors that point tangent to the circle so that each is the same length.
