PDF-Catapults and Projectile Motion Parabolic Equations OBJECTIVES CORE LE

Students will use catapults to explore projectile motion and parabolic equationsStudents will verify the kinematic equations using reallife data113 The student will apply addition subtraction m. Farsquaad. . Problem Statement. Torsion is not strong enough to propel the objects. . . Base has to be very stable. . . Need the right measurements to insure success when launching. . Operation and Application. 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). . 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. 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. acceleration = a = constant. © 2015 Pearson Education, Inc..

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.. Catapults have been integral to siege warfare since antiquity. . Ancient . Catapults were one of the most effective weapons in siege warfare. . Various . types of Catapults have been used by the Greeks, Romans, and Chinese. The first catapults were early attempts to increase the range and power of a crossbow. . 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.. 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 AP Statistics Chapter 1 - Review 2013 Mrs. White AP ExamTopic Outline Topic Exam Percentage Exploring Data 20%-30% Sampling & Experimentation 10%-15% Anticipating Patterns 20%-30% Statistical Inference 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.
