PPT-Projectile Motion

Objects Projected Horizontally Horizontal projectile motion   horizontally the velocity is always constant 0 vertically the initial velocity y is always zero vertically . 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. :. Place on Your Desk:. *Calculator & Protractor. 1) . Which instrument can we use in the lab to measure force (Newton's)?. . . . . . . Agenda. Warm-Up . 5 min. Vocab. Words . 10 min. Mr. Barker. Angry Birds need your help.. Solution. The vertex is at (6.5, 11). Solution. Solve for A and plug it in.. Projectile Motion. Who is in the air longer?. At only 5’7”, he won the 1986 NBA Slam Dunk Championship.. 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. explain . and . justify . the theory of projectile motion to a number of sports.. Some are able to . predict . the factors that affect projectile motion.. Homework. Flipped learning activity on Angular motion.. 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.. The horizontal acceleration. The vertical acceleration. The horizontal component of the velocity. All of the above.. a. less than 0.5 s. . . b. more than 0.5 s.. c. 0.5 s.. A bullet is fired horizontally and hits the ground in 0.5 seconds. If it had been fired with twice the speed in the same direction, it would have hit the ground in ____. (Assume no air resistance.). 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.. 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”. 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?. 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 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.
