PPT-Parametric Equations and Projectile Motion

Honors Trigonometry Chapter 8 Section 6 What is projectile motion What variables can you control What sports use projectile motion Ovida Fentz hits a baseball so that it travels at a speed of 120 feet per second and at an angle of 30 degrees to the horizontal Assume his bat contacts the ball at a height of 3 ft above the ground. &. Lab Activity. Force (. F. ). : strength or power applied upon an object.. F = mass * acceleration. Definitions. Mass (. m. ). : the quantity of matter (atoms/particles) in the object. Gravity (. A projectile is an object upon which the only force acting is gravity. .. An . object dropped from rest is a projectile (provided that the influence of air resistance is negligible). .  . An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). . Section 10.4b. A baseball is hit when it is 3 . ft. above the ground. It leaves the bat. with initial speed of 152 . ft. /sec, making an angle of with the. horizontal. At the instant the ball is hit, an instantaneous gust of. What is Projectile motion?. . Projectile. . motion refers to the motion of an object projected into . the . air at an angle. .. A . projectile . has a single force that acts upon it - the force of . 2D Motion. Moving Motion Forward. Velocity, Displacement and Acceleration are VECTORS. Vectors have magnitude AND direction. So far, direction has been positive and negative. Motion with Vectors. Motion concepts combine with Vector concepts to allow us to represent motion in multiple directions simultaneously. i. n the (. x,y. ). plane. Introduction. This chapter focuses on . P. arametric equations. Parametric equations split a ‘Cartesian’ equation into an x and y ‘component’. They are used to model projectiles in Physics. Please treat them well. Chong Ho Yu. Parametric test assumptions. In a parametric test a sample statistic is obtained to estimate the population parameter. . Because this estimation process involves a sample, a . Nature of science: . Observations: The ideas of motion are fundamental to many areas of physics, providing a link to the consideration of forces and their implication. The kinematic equations for uniform acceleration were developed through careful observations of the natural world.. September 26 and September 29, 2014. Projectile Motion Problem Solving Steps. To solve projectile motion problems, you must separate the horizontal and vertical components of motion.. Resolve the launch velocity to find the . What is a projectile?. A body in free fall that is subject only to the forces of gravity and air resistance. Motion of bodies flung into the air. Occurs in many activities, such as baseball, diving, figure skating, basketball, golf, and volleyball. Physics. Coach Taylor. Broad Run High School 2010-2011. Objectives. Recognize that the vertical and horizontal motions of a projectile are independent.. Relate the height, time in the air, and initial vertical velocity of a projectile using its vertical motion, then determine the range.. MAT 493. Definition. Projectile Motion is defined as the motion of an object near the earth’s surface. . ‘Near’ .  Gravity extremely influential to the trajectory of an object. history. Aristotle – projectiles pushed along by some external force that was transmitted through the air called “impetus”. 7-2 Projectile Motion Independence of Motion in 2-D Projectile is an object that has been given an intial thrust (ignore air resistance) Football, Bullet, Baseball Moves through the air under the force of gravity Ged. Ridgway. Wellcome Trust Centre for Neuroimaging. UCL Institute of Neurology. SPM Course. October 2011. Contents. Historical background. Positron emission tomography (PET). Statistical parametric mapping (SPM).
