The projectile motion
. Positive direction towards right. .Positive y-axis upward as the object moves downward. .Value of y will always be negative- .Acceleration in y direction is - g .In free fall acceleration in x direction is zero . Vertical motion along y direction does not effect the horizontal x motion .vy=-gt .Horizontal velocity component remains constant .Vertical comppnent increase linearly with time .Vo instant velocity .Vx = vox= vocos Vy= vo sin- gt 1/2g vopower^2 sino^2 = maximum height R=vo/g sin20 Vertical component= of acceleration= is equal to the acceleration due to gravity g=-g
