## Projectile MotionEdit

Projectile Motion refers to any motion moving under the effect of gravity. This kind of motion is famous for its trajectory being in the shape of a parabola.

## Analysis (two dimensional space)Edit

Suppose the object is projected at an angle at a height h with an initial velocity of v with a gravity of g. When on Earth g will equal 9.8 m/s^{2}.

The components of velocity in horizontal (x-) and vertical (y-) directions are:

By using , The x- and y- coordinates of the object are

which are functions in time.

By eliminating t,

which shows that the trajectory is a parabola

### Velocity at any time tEdit

The magnitude of the velocity at any time t is given by

and the direction is given by

### Time of flightEdit

To solve for the time of flight, we set y(t)=0

- or

### Horizontal rangeEdit

After , the x-coordinate of the object is given by

### Maximum heightEdit

The maximum height is given by

where h is the initial height
