## High School Physics : Circular Motion

The acceleration of an object moving in a circle can be determined by either two of the following equations. The equation on the right above is derived from the equation on the left by the substitution of the expression for speed. The net force F net acting upon an object moving in circular motion is directed inwards. While there may by more than one force acting upon the object, the vector sum of all of them should add up to the net force. In general, the inward force is larger than the outward force if any such that the outward force cancels and the unbalanced force is in the direction of the center of the circle.

Downlaod Click here Pages: 3, Size: A body is allowed to slide on a frictional less track from rest under-gravity. The track ends in a circular loop of diameter D. What should be the minimum height of the body in terms of D, so that it may successfully complete the loop? A body of mass gram, tied at the end of a string of length 3 m rotates in a vertical circle and is just able to complete the circle. If the tension in the string at its lowest point is 3.

This action cannot be undone. This will permanently delete All Practiced Questions. A metal ring of mass m and radius R is placed on smooth horizontal table and is set rotating about its own axis in such a way that each part of the ring moves with a speed v. Tension in the ring is:. If he turns at double the speed, the tendency to overturn is. ## High School Physics : Circular Motion

### Mechanics: Circular Motion and Gravitation

Ellen is swinging a yo-yo in a circular path perpendicular to the ground. The yo-yo moves in a clockwise direction with a constant speed of. This means that, even though the speed is constant, the direction is always tangent to the edge of the circle. If the circle below represents the path of the yo-yo, and it moves in a clockwise direction, then the velocity at the bottom of the path will be to the left. The magnitude of the velocity is constant, so the final answer will be. If the force applied remains the same, then that means that the torque and the lever arm are directly proportional: when one increases the other increases as well.

Determine the magnitude of the acceleration of the car. If the radius of the motion is 0. Assume all other parameters stay constant except that noted in the description of the change. Of course, the object would have to be forced differently to keep the speed the same if the mass changes. List the standard lab apparatuses needed to make the measurements and the calculations a student can make with the measurements to determine the acceleration. This type of question is very important for your test preparation.

These MCQs are important from the exam point of view. By practicing with these questions students will get acquainted with the key concepts which must be prepared to score high marks in the objective type questions in the Class 9 Science Annual Exam If the displacement of an object is proportional to square of time, then the object moves with:. It implies that the boy is:. Average speed. Which of the following statement is correct regarding velocity and speed of a moving body? #### Related Categories
