Projectile Motion

Hello this is an easy way to understand the projectile motion.

Things to remember:

1. Vt= Vo+at

2. A=Vt-Vo/time

3. S=Vot-1/2*a*t^2

4. Vt^2=Vo^2+2*AS

In Projectile motion there must be gravity acting on this motion as it is going in reverse of the gravity.

So,

1.Vt= Vo+g*t

2.S= Vot-1/2*g*t^2

3. Vt^2=Vo^2+2*gS

In projectile motion there must be an angle, speed, time and distance on the motion.

1.At the X axis/Range

Velocity of X will always be the same till it reach the ground.

But remember to count the angle of this motion.

E.g Angle: 60 Degree, Initial Speed(Vo): 10m/s

Vox = Cos60 * 10= 5m/s

Because the velocity of x is always the same so,

Vox=Vx

To determine the range it's just like counting distance on speed formula

X(range)=Vox*t

V=Vox+at

X(range)=Vox*t-1/2*g*t

This one is for the Y(height) it is abit different to count the components of Y because in different height the speed will change by the time it is going.

So,

1.At the Y axis/Range

Velocity of Y is always different as it has the effect of gravity.

E.g Angle: 30 Degree, Initial Speed(Vo): 10m/s

Voy = Sin30 * 10= 5 m/s

Because the velocity of y is not always the same so,

Vy = Voy-g*t

To determine the height is just like this,

Y=Voy-1/2*g*t^2

Time on Maximum height: TMaxHeight (TMH)=Voy/g

Maximum height: Voy^2/2g

Time on Maximum range: TMH*2

Maximum Range: Vox*Time on Maximum Range

Calm down this is easy ^^ Keep up your smile

This is Magnitude and direction of velocity at certain time (we've found out the elements with several shown formulas)

V=

Wish you to be happy, keep calm, never lose hope, do good deeds, smile, don't talk trash and you will be happy Thankyou ^_^
