**Unit 8 Uniform Circular Motion**
The pages that were picked up at the beginning of class were 1, 2, 3, 4, and a reading guide. We started a new unit today and it was announce the test will be next Friday and the reading guide will be due then.

Objectives: Pass back Test Review Test (Some answer may be marked wrong, but might be right so talk to Mr. Manning) Hand in Complex Machine Start Page 2

Page 2 Velocity, Force, and Acceleration in UCM Activities Question 1) Mr. Physics is attached to a rope and swung around in a circle. What will the direction of Mr. Physics be if the rope is released at the time shown. Predictions Our class predictions were drawn on the problem as shown below J.S.Miller explanation When released Mr.Physics would have traveled straight out from the point of release because of the direction of the velocity of Mr. Physics.

The other questions have not been discussed yet due to the length of time to review the test.

Page 3 Circular and Rotational Motion Terms Notes and Worksheet Uniform Circular Motion: When an object travels at a constant speed in a circular path. The velocity's direction is tangent to the circle itself. To find tangential speed we need to use the variables below: V = tangential speed. f= frequency = rotational speed Speed = distance/time Distance = circumference = 2πr Speed = 2πr/time for one revolution Time = T = Period = (T=1/f ) So using this we can find the tangential speed by using Speed = 2πr/ Time
