PPT-Vectors and projectiles Which of the following remains constant while a projectile is

The horizontal acceleration The vertical acceleration The horizontal component of the velocity All of the above a less than 05 s b more than 05 s c 05 s A bullet is fired horizontally and hits the ground in 05 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. &. 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). . :. 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. :. HOMEWORK CHECK. Place on your desk:. *Calculator. *. Orange. homework chart . *. Vector Lab. 1) . An object that is projected and continues in motion by its own inertia is called_______________.. CS 282. Review of projectile physics. Examine gravity projectile model. Examine drag forces. Simulate drag on a projectile. Examine wind forces. Simulate wind affecting a projectile. Overview. Acceleration. 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. that . is given an initial . horizontal or angular velocity. , and then follows a path determined entirely by gravity. .. Projectiles. by Greg Royal. Drury High School. North Adams, Massachusetts. Projectiles in sports. 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. Adam . Zidek. Key Elements for a projectile. Built off Actor Class. Collision Volume. Block all Dynamic. Static Mesh. Particle System(If Desired). Rotating Movement Component(If Desired). *Projectile Movement Component. 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.. Free fall . with an initial horizontal velocity. (assuming we ignore any effects of air resistance). The curved path that an object follows when thrown or launched near the surface of Earth is called a . Vectors, Shmectors. Objectives. 1. Distinguish between a scalar and a vector.. 2. Add and subtract vectors by using the graphical method.. 3. Multiply and divide vectors by scalars.. Vectors, Schmectors. 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?.
