Class 11 Physics Motion In A Plane Motion in a plane with constant acceleration

Motion in a plane with constant acceleration

Motion in a plane (two dimensions) can be treated as two separate simultaneous one-dimensional motions with constant acceleration along two perpendicular directions. X and Y directions are hence independent of each other.

If v0 being the velocity at time 0, the displacement can be written as:

x = x0 + v0xt+ ½ axt2 and y = y0 + v0yt+ ½ ayt2

Velocity

Velocity in terms of components

Displacement

v = v0+ at

vx = v0x + axt

vy = v0y + ayt

r = r0+ v0t+ ½ at2
