PPT-Uniform Circular Motion, Work and Energy Competition

A bunch of stuff youll see on the midterm exam Question 1 Give the formula for speed in a circle of radius r Give the formula for centripetal acceleration Give the formula for centripetal force. 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. . Angular Measure, Angular Speed,. and Angular Velocity. Bellwork. . 1. A tube is been placed upon the 1 m-high table and shaped into a three-quarters circle. A golf ball is pushed into the tube at one end at high speed. The ball rolls through the tube and exits at the opposite end. Describe the path of the golf ball as it exits the tube.. Circular Motion Lab Results. Part 1: Radius’ effect on velocity. Mass, centripetal force kept constant. Part 2: Mass’ effect on velocity. Radius, centripetal force kept constant. Part 3: Force’s effect on velocity. © 2016 Pearson Education, Inc.. Goals for Chapter 6. To understand the dynamics of circular motion.. To study the unique application of circular motion as it applies to Newton. '. s law of gravitation.. Can you change your velocity while not changing your speed?. v. F. Consider the above situation.. According to Newton . S. econd law, what must the object be doing?. It is accelerating so the velocity must be changing.. Uniform Circular motion. For an object moving on a circle at constant speed. The . speed is constant. , but the . direction is not. Acceleration is a change in velocity, but speed is constant. The change in velocity is only in its direction. Circular Motion. Objectives:. 1. Solve problems involving centripetal acceleration.. 2. Solve problems involving centripetal force.. 3. Explain how the apparent existence of an outward force in circular motion can be explained as inertia resisting the centripetal force.. Doug . Backman. Module 3. OMB Circular A-110. Uniform Administrative Requirements. Doug Backman. Exploring Research Administration…for CONCEPT to COMMERCIALIZATION. AGENDA. Authority & Definitions. Vocab. Energy – the ability to do work or cause change. Motion – an object’s position changes relative to another object. Force – a push or pull. Work – when the force exerted is in the same direction as the motion. Here are some laundry suggestions that you should consider implementing on a school uniform of your children.
