For example, if you are analyzing the motion of a ball thrown downwards from the top of a cliff, it may make sense to define the positive direction downwards since the motion of the ball is solely in the downwards direction. If this is the case, g takes a positive value. Example 2. ...
Projectile motion occurs when objects are fired at some initial velocity or dropped and move under the influence of gravity. One of the most important things to remember about projectile motion is that the effect of gravity is independent on the horizontal motion of the object. The independence o...

part about St. Andrews may simply be golfing legend, since the course there is regarded as the birthplace of golf in the fifteenth century.) Whatever the case, it is true that a scored ball has a longer trajectory, again as a result of the effect of air resistance on projectile motion....

1 2 S at . a. What do the letters S, a and t stand for in this equation? b. This equation could also be written as 2 16 d t , which is the distance, d, in feet, that an object falls due to gravity as a function of time, t, in seconds. Explain why, in this case, ...
Projectile motionCaputo derivativeFractional differential equationsMittag-Leffler functionIn this paper we propose a fractional differential equation describing the behavior of a two dimensional projectile in a resisting medium. In order to maintain the dimensionality of the physical quantities in the system,...
As we said, horizontal projectile motion equations are a particular case of general formulas. We don't need to specify the launch angle, as it's parallel to the ground (so the angle is equal to 0°). As a result, we have only one component of initial velocity – Vx=VVx=V, whereas...
What are the kinematic equations for projectile motion? The kinematic equations for projectile motion are: 1. x = x0 + v0xt + 1/2at2 2. y = y0 + v0yt + 1/2at2 3. vx = v0x + at 4. vy = v0y + at 5. vy = v0y + at How do these equations describe projectile motion?
