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) .

In a projectile “curved path” the vertical and horizontal vectors are ____________of each other.. Tennis ball. Golf ball. Football. Softball. Soccer ball. Bullet. Hockey puck. Basketball. Volleyball. Arrow. Shot put. Javelin. These are all examples of things that are . projected. , then go off under 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.. 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?.
