I came across some random study materials, and that’s where I saw this. Secondly, is there such an equation as Equation $\left(2\right) ?$ I mean, is it a correct equation? I didn’t find it in my book, or in any other book. ![]() But I can’t seem to figure out whether it’s positive or not. I get a situation (usually, its a video analysis problem) in which. The kinematic equations for a simple projectile are those of an object. I have a doubt it’s not (I am probably wrong). A projectile is any object with an initial horizontal velocity whose acceleration. Derivation for the formula for a maximum height of projectile. All the 3 equations of motion are valid in a projectile motion. At the point of maximum height, the vertical component of velocity becomes zero. My question is: I’m not able to figure out if discriminant of Equation $\left(2\right)$ is positive, is it? In order to get two values of $\theta$ from that equation, its discriminant must be positive. The only force acting on the object in the projectile motion is the force of gravity with an acceleration of gravity g 9.8 m/s on Earth. This is again an equation that represents Parabola. As you see this can be rewritten in the form y ax bx2 where a and b are constants. From equation 4 above, we get the trajectory path of a projectile as y (tan) x (1/2) g. The object is called a projectile, and its path is called its trajectory. Equation of the Trajectory of a projectile is a parabola. But just wanted to get it across better.) A projectile will follow a curved path that behaves in a predictable way. Here are the sections within this lesson: What is a Projectile Projectile Formula Locating the Maximum Height of a Projectile Using Algebra Example Problem. Projectile motion is the motion of an object thrown (projected) into the air when, after the initial force that launches the object, air resistance is negligible and the only other force that object experiences is the force of gravity. I could’ve asked my question directly, without typing the equations. (I had to type everything just to make my question clear. What it means in physical terms (according to what I read) is, if we are projecting a projectile with an initial velocity $u$ and we want it to touch a particular coordinate $\left(x,y\right) ,$ then we can make it pass through the given coordinate by projecting it at two different angles $\theta_1$ and $\theta_2$ that we get from Equation $\left(2\right) ,$ and no more than these two angles (keeping magnitude of initial velocity $u$ the same). This is what I read: If values of $u$, $x$, and $y$ are constants, then we would get two values of $\tan\theta$, i.e., two values of angle of projection $\theta :$ $\theta_1$ and $\theta_2. ![]() button Objects that are dropped: If an object is dropped, it is. Recall Newtons second law of motion: if at any time t. Notice that this formula is a quadratic function, which means its graph will be a parabola. This is the locus equation of a projectile projected from the ground at an angle $\theta$, with an initial velocity $u$ : We (you) will derive parametric equations that describe the trajectory of this projectile.
