Projectile Motion (Horizontal and Vertical)
- 2. Horizontal Dimension Vertical Dimension
- 4. When an object moves both vertically and horizontally, it is called PROJECTILE MOTION. A single force acts upon it – the force of gravity. If there were any other force acting upon an object, then that object would not be a projectile.
- 5. A. An object at an elevated point dropped from rest is an example of a projectile (provided that the influence of air resistance is negligible). B. An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). C. And an object which is thrown upward at an angle with the horizontal is also a projectile (provided that the influence of air resistance is negligible).
- 6. A projectile is any object that once projected or dropped and continues to move by virtue of its inertia and influenced only by the downward force of gravity. Most of the projectile motion travels in a curved path called trajectory.
- 7. Path of a Projectile Neglecting air resistance, the path of a projectile is a parabola
- 9. A stone is thrown with an initial horizontal velocity of 10 m/sec from the top of a tower 200 meters high. 1. What is the horizontal velocity of the stone 2 seconds after being thrown? 2. How far does the stone travel horizontally after 2 seconds? 3. What is its velocity upon hitting the ground after 6 seconds? 4. How far has it gone vertically downward as it hits the ground in 6 seconds?
- 10. 1. What is the horizontal velocity of the stone 2 seconds after being thrown? The horizontal velocity remains constant (10 m/s) in its entire flight.
- 11. 2. How far does the stone travel horizontally after 2 seconds?
- 12. 3. What is its velocity upon hitting the ground after 6 seconds?
- 13. 4. How far has it gone vertically downward as it hits the ground in 6 seconds?
- 14. A rock is thrown with a velocity of 23.7m/s horizontally off the top of an elevated hill. If the time it takes to reach the ground is 5.70 seconds. What is the height of the hill?
- 15. An arrow is fired directly horizontal off a cliff with a velocity of 65.56 m/s in 1.43s. What is the range of the arrow?
- 16. A pool ball leaves a high table with an initial horizontal velocity of 2.4 m/s at 0.35s. a. Predict the height of the table. b. Predict the horizontal distance between the table's edge and the ball's landing location.
