PH-UY 1013 Lecture Notes - Lecture 1: Vix, Parabolic Trajectory
Document Summary
Projectile- any object that is launched by some force and continues to move by its own inertia. Path of a projectile is referred to as its trajectory. Motion of a projectile is best described by separating its motion into horizontal (x) and vertical (y) components of the vector quantities displacement, velocity and acceleration. A projectile is any object upon which the only force is gravity, Projectiles travel with a parabolic trajectory due to the influence of gravity, There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9. 8 m/s/s, down, The vertical velocity of a projectile changes by 9. 8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion. When solving these projectiles, we usually also form a table as follows.
