Here you can evaluate your knowledge about circular motions by answering the question listed below.

## High School Physics : Circular Motion

A what is the average velocity. Circular motion worksheet 1 of 1 circular motion worksheet name period date 1. What is the cyclists acceleration.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. Two children sit on a merry-go-round. If the children are in a straight line form the center, which child has a greater speed? The child from the center. When moving in a circle, the distance is the circumference, and each rotation takes exactly one period. We can substitute into the velocity formula. If the children are in a straight line, that means that their periods how long it takes to make one revolution will be the same.

The only thing that changes isthe distance from the center.

Reordering sentences class 10

Since radius is in the numerator, we can conclude that increasing the distance from the center will increase the velocity. 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. The length of the lever arm, in this problem, is the length of the wrench; thus, increasing the length of the wrench will increase the amount of torque generated, without requiring a change in the force applied.

A car driving on the highway is moving at 60 miles per hour. As the car nears an exit ramp, the car slows to 35 miles per hour, a speed that is maintained throughout the circular path of the exit ramp.

What force is keeping the car on its path i. The correct answer is centripetal force. In a free body diagram, this is the force that would be directed towards the center of the circular path; in circular motion, acceleration and net force are always in this direction.

Momentum is not a measure of force and is not particularly relevant to this question. A ball attached to a string is moving counterclockwise in a vertical circle. If the string is cut exactly at the point where the ball is at the top of its motion the top of the circlewhat direction will the ball move in initially? In circular motion, velocity is tangential to the circular path. Since the object is moving counterclockwise, at the top of the circle this tangent line points to the left.

It may help to draw a diagram to better visualize this motion. Centripetal acceleration is the acceleration towards the center when an object is moving in a circle. Though the speed may be constant, the change in direction results in a non-zero acceleration. Centripetal force is the force that constantly moves the object towards the center; it is what keeps the object moving in a circle rather than flying off tangentially to the circle.

The formula for force is. To find the centripetal force, we need to find the centripetal acceleration. If we start with the linear understanding of velocity,we can apply the same concept here. Our velocity should be the change in distance over the change in time. In this case, we don't have a definite time,but we do have a period in terms of one complete loop. We can set up an equation for the period using the circumference of the circle as our distance:.
