PPT-Projectile Motion Introduction

Physics Coach Taylor Broad Run High School 20102011 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. &. 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 (. 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. Ideal Projectile Motion. Ideal Projectile Motion. What do we mean by the word “ideal” here?. T. he projectile behaves like a particle moving in a. vertical coordinate plane.. The only force acting on the projectile during its. Objects Projected Horizontally. Horizontal projectile motion:.  . horizontally . the velocity . (. ) is . always constant .

This lecture will help you understand:. Projectile Motion. Fast-Moving Projectiles – Satellites. Circular Satellite Orbits. Elliptical Orbits. Kepler. '. s Laws of Planetary Motion. a = 0 case. no acceleration  velocity is constant  v = v. i. position vs. time  . x. f. = x . i. + v t,. x. i. is the starting . position, . x. f. is the ending position. acceleration = a = constant. Place on your desk:. *. Calculator & PROTRACTOR. *. Orange. homework chart . *. Horizontal Distance WS. 1) . In a projectile “curved path” the vertical and horizontal vectors are ____________of each other.. 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”. Chapter 3 pg. . 81-105. What do you think?. How are measurements such as mass and volume different from measurements such as velocity and acceleration?. How can you add two velocities that are in different directions?. Biomechanics Projectile motion & Fluid mechanics Projectiles A projectile is anything that goes off the ground. In sport that could be a rugby ball that has been kicked or a tennis ball that has been struck. Problems will be solvable using the equations of uniform acceleration. . .  . Projectile motion. This section is devoted to understanding the motion of projectiles. A projectile is an object upon which the only force acting is gravity.
