A projectile is an object that is given an initial velocity and is acted on by gravity. The initial velocity v i is the velocity of the object before acceleration causes a change.

Initial velocity final velocity acceleration time.
Physics formula initial velocity. The initial velocity is articulated as. Finally subtract your first quotient from your second quotient to find the initial velocity. This path is the object s trajectory.
Formulas for initial velocity. And because they are the kinematic equations are applied to each motion the horizontal and the vertical motion. But to do so the initial velocity and launch angle must be resolved into x and y components using the sine and cosine function.
The horizontal and vertical motion of a projectile are independent of each other. Three initial velocity formulas based on equations of motion are given below if time acceleration and velocity are known. The path the object follows is determined by these effects ignoring air resistance.
Then divide that number by 2 and write down the quotient you get. The physics classroom explains the details of this process. Velocity will have the magnitude as well as a specific direction.
The general way to calculate the constant velocity of some object moving in a straight line is to divide the distance by time taken. U v at. In simple way it is v frac d t in other way the velocity formula physics is v frac change in position time.
After accelerating for some amount of time the new velocity is the final velocity v f. Final velocity 2 initial velocity 2 2 acceleration distance. The velocity equation is.
Obviously this velocity at time interval t 0. It is represented by letter u. To find initial velocity start by multiplying the acceleration by the time.
The equation for velocity is one of the fundamental formulas in physics. V avg xf x0 tf t0. The initial velocity is formulated as.
While many physics concepts have scientific definitions different from their colloquial use your intuitive perception of velocity is probably rather similar to its definition within physics. Thus velocity at which motion start is the initial velocity. They are four initial velocity formulas.
Next divide the distance by the time and write down that quotient as well. 1 if time acceleration and final velocity are provided. Initial velocity is the velocity at time interval t 0 and it is represented by u.
U v at. Velocity acceleration and distance this equation applies to objects in uniform acceleration. It is the velocity at which the motion starts.
The trajectory has horizontal x and vertical y components.
