projectiles launched horizontally have no initial vertical velocity. as a result, the vertical motion is identical to that of a dropped object. the downward velocity increases due to the acceleration due to gravity.
Lecture Notes. (Projectile Motion) Intro: the previous chapters have considered motion mainly in a straight line; this is called rectilinear motion (Latin rectus = ‘straight’ and linea = ‘line’) this chapter will be looking at motion in two dimensions, that is, curvilinear motion.
PROJECTILE MOTION Objectives † Distinguish between a vector quantity and a scalar quantity. (5.1) † Explain how to find the resultant of two perpendicular vectors. (5.2) † Describe how the components of a vector affect each other. (5.3) † Describe the components of projectile motion. (5.4) † Describe the downward motion
This set of equations describes a kinematics model for projectile motion based on Newton’s first and second laws. There are two important facts to be noticed: (a) the distance the ball travels in the X direction is directly proportional to the time of flight; which is due
Projectile Motion Definition: • body of mass m launched with speed v0 at angle θ from the horizontal; • air resistance F P res = − b v P , b = nonnegative constant (possibly zero) x z F = –mg m θ z v 0 Prerequisites: • fundamentals of Newtonian mechanics • motion in one dimension, with and without res-istance Why study it?
