II Uniform Circular Motion A. Nomenclature 1. Speed – magnitude of an objects rate of motion (no direction‚ scalar quantity) 2. Velocity – speed and direction of an objects motion (vector‚ mag & direction) 3. If a car’s speed is constant but direction is changing‚ velocity is changing. 4. 2 ways to change velocity (change speed or change direction). 5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed

Does Violence Motivate? How can you define violence? Does it only have a physical definition‚ like attacking another person? Or is it defined the way Gabriella Nilsson‚ author of Balls Enough‚ does‚ with a much broader definition‚ including not only physical violence but also emotional violence? Under her definition‚ everything from yelling to voicing displeasure can be defined as violence. In short‚ humiliating anyone in any way is violence. But at what point do we cross from her definition of

DYNAMICS -studies the relationship of motion to the forces that causes it. Types of Forces: (a) Normal Force‚ n :When an object rests or pushes on a surface‚ the surface exerts a push on it that is directed perpendicular to the surface. (b) Friction Force‚ f : In addition to the normal force‚ a surface may exert a frictional force on a object‚ directed parallel to the surface and opposite the motion or impending motion of the object. f s = µ s n - static friction‚ maximum friction before the object

Motion Analysis: Basketball Jump Shot The main joints involved in a basketball jump shot include the hip‚ knee‚ ankle‚ shoulder‚ elbow‚ and wrist. All of these joints flex and extend. The jump shot can be split into three parts: the set-up‚ the jump and release‚ and the post-release. The set-up involves a lot of flexion and extension of the hip‚ knee‚ ankle‚ and shoulder. Hip flexion occurs first and flexion of both knees until the thighs are parallel to the ground follows closely. Knee flexion

ROTATIONAL MOTION CENTRE OF MASS AND ROTATIONAL MOTION INTRODUCTION- For describing the motion of rigid bodies‚ we shall introduce the key concept of ‘centre of mass’. This concept enables us to understand how we can apply justifiably the Newton’s laws of motion‚ in essentially the same form to objects of large size including even the astronomical objects like the planets and the stars. KINDS OF MOTION OF A RIGID BODY- A rigid body may have three kinds of motion- (1) Pure Translation Motion- in such

throws a curve ball‚ or maybe why the bat breaks‚ and how a homerun is hit. Well just know physics has a lot to do with that and more. I will try to explain to you how these things happen and more during this essay. There are many forces that take place in baseball. The pitcher applies forces to a ball‚ in order to strike out the batter. The pitcher determines the speed and velocity of the ball. The pitcher can make the ball do different and unique things. For instance a curve ball is one example;
