This curved path was shown by Galileo to be a parabola, but may also be a straight line in the special case. l = pr = mvr = (2) (3 cos θ) = 12 Notice that the thetas cancel, and this answer is valid for P anywhere on the line of travel of the particle. Thus we have shown that the angular momentum of the particle is the same in all places. This agrees with our theorem that a net torque is required to change the angular momentum of a particle.

**Projectile motion** is a form of **motion** experienced by an object or particle (a projectile) that is projected near Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are passive and assumed to be negligible). This curved path was shown by Galileo to be a parabola, but may also be a straight line in the special case.

In **angular** **motion**, we use 'θ' for the same to quantify the **angular** distance, and it is measured in radians. In simple words, **angular** velocity is the time rate at which an object rotates or revolves about an axis. **Angular** velocity is represented by the Greek letter omega (ω, sometimes Ω).
