Projectile Motion || Grade 9 Physics || K to 12 Science
- 1. Projectile Motion P R E S E N T E D B Y S U J H S P H Y S I C S T E A C H E R S G R A D E 9 P H Y S I C S
- 2. Learning Targets I can describe the horizontal and vertical motions of a projectile. I can investigate the relationship between the angle of release and the height and range of the projectile.
- 3. Studying projectile motion is like looking at an optical illusion.
- 4. PROJECTILE MOTION A type of motion wherein an object called a projectile is thrown in the air and moves a curved path under gravity alone
- 5. Types of Projectiles Horizontally launched Projectile Nonhorizontally launched Projectile 1 2
- 6. No resistance in any form Constant horizontal velocity Zero horizontal acceleration (ax = 0) Horizontal distance: Range HORIZONTAL MOTION X-COMPONENT VERTICAL MOTION (FREE FALL) Y-COMPONENT COMPONENTS OF PROJECTILE MOTION Acted upon by gravity Accelerating vertical velocity Constant vertical acceleration (g = ay = - 9.8 m/s2) Vertical distance: Maximum Height
- 7. y HORIZONTAL MOTION: Has an initial horizontal velocity that is constant (neglecting air resistance) ax = 0 VERTICAL MOTION: accelerating due to gravity ay = -9.8 m/s2 PROJECTILE MOTION - Has a curvilinear path called trajectory - Vertical & horizontal components are independent of each other Projectile Motion
- 8. INDEPENDENCE OF THE HORIZONTAL & VERTICAL COMPONENTS OF PROJECTILE MOTION
- 9. PROJECTILE MOTION o Neglecting Air Resistance o Under the sole influence of gravity Horizontal velocity is always constant Vertical velocity decreases as the projectile moves up and increases while it moves down along its trajectory Velocity Horizontal acceleration is always zero Vertical acceleration is always equal to the acceleration due to gravity, -9.8 m/s2 (on Earth) Acceleration Horizontal distance – range Vertical distance – maximum height Distance
