PPT-Chapter 5: Circular Motion; Gravitation

Curves Forces act in straight lines An object will move in a straight line if there is NO force acting on it or if the net force acts in the direction of the motion BUT what if the net force acts at an angle to the motion. And 57375en 57375ere Were None meets the standard for Range of Reading and Level of Text Complexity for grade 8 Its structure pacing and universal appeal make it an appropriate reading choice for reluctant readers 57375e book also o57373ers students Chapter 5. Kinematics of Uniform Circular motion. An object that moves in a circle at constant speed, v, is said to be under uniform circular motion. . The magnitude of velocity remains constant.. The direction of velocity changes continuously.. Circular motion. We will be looking at a special case of kinematics and dynamics of objects in uniform circular motion (constant speed). Cars on a circular track (or on a curved road). Roller coasters in loop. express angular displacement in radians. . understand and use the concept of angular velocity to solve problems. . recall and use . v = r. ω. to solve problems. . describe qualitatively motion in a curved path due to a perpendicular force, and understand the centripetal acceleration in the case of uniform motion in a circle. .
