- 2. Any object that continues in motion by its own inertia and is influenced only by the downward force of gravity (and air resistance) - an object dropped from rest is a projectile - an object thrown straight upward is a projectile - an object thrown upward at an angle to the horizontal
- 4. Projectile Motion Combines Vertical Motion and Horizontal Motion Two Fundamental Principles - The horizontal acceleration is zero since horizontal velocity remains constant throughout the motion. - The vertical acceleration is subject to the acceleration due to gravity g verically downwards.
- 5. Projectile Motion Combines Vertical Motion and Horizontal Motion • The vertical motion of a projectile is not affected by its horizontal motion -The vertical motion of a projectile is identical to an object in free fall • The horizontal motion of a projectile is not affected by its vertical motion - the projectile will travel the same horizontal distance as it would if it were simply rolling on a flat surface in the absence of friction
- 12. Projectile Motion and Complementary Angles • Different launch angles result in different horizontal distances (Range) traveled by the projectile – Same range is obtained from two different launching angles when the angles add up to 90°. • Object launched at an angle of 60 has the same range as if it were thrown at an angle of 30.
