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
Describe the properties of projectile motion; Apply kinematic equations and vectors to solve problems involving projectile motion
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.
Projectile Motion • Projectiles > objects given an initial velocity that then move under the force of gravity • Trajectory > the path followed by a projectile > The path is a curve called a parabola 1 2
Projectile Motion: Practice Problems with Solutions Physexams.com 1. A missile is shot horizontally from the top of a 500m cliff with an initial speed of 300m/s (a) Find the time it takes for the missile to hit the ground. (b) What is the range of the missile? (c) Calculate the velocity of the missile just before it hits the ground.
Projectile Motion Formula Sheet. You can find the proofs of these results in our tutorial videos.
