Projectile Motion

Projectile Motion
Kristin Lietazu and Maggie Allen

Objective:
The purpose of this experiment is to help students earn the motion of a projectile at different angles.
hypothesis:
An important special case of two-dimensional motion is cognise as projectile motion. A projectile moves at a constant speed in the flat direction while experiencing a constant acceleration of 9.8m/s2 downwards in the straight direction. The speed in the horizontal direction (vx) is constant end-to-end the projectile motion. It is used to predict the position at every(prenominal) time in the horizontal direction, which can be bring, by using the equation:
x = vxt = v0 cos?0t
Where,
x = the horizontal displacement
vx = pep pill in the x direction
v0 = initial velocity
t = time
?0 = initial angle.
The speed in the plumb direction constantly changes because of gravities downward pull. The equation that predicts the vertical velocity at any time vy is
vy = v0y + ayt
Where
vy = velocity in the y direction
v0y = initial velocity in the y direction
ay = acceleration in the y direction.
If a projectile is pink-slipped at any angle the object will fall vertically in time, which is represented by the equation:
y = v0yt + ½ayt2 = v0sin?0t - ½(-9.

Procedure:
situation I
First we set up the projectile launcher and build the height from the ground to the height of where the thud would be ejected. indeed (from the medium range position) we shot the ball and noted where it beauty the floor and placed the carbon paper (on top of a sheet of paper) down and tapped it. After tapping it we measured the distance from the where the ball would be fired to the keenness of the carbon paper. thusly we fired the ball 10 times. Next we measured the distance from the edge of the paper to each mark on the carbon paper. Then we added those values to the first horizontal value measured and found the average value. Finally we calculated the time it took the ball to take up the paper and the initial velocity...If you want to get a amply essay, order it on our website: Orderessay
