Describing velocity

^Describing velocity

4. Velocity of a projectile is defined as

5. Using v – t relation for the motion O to P along x & y axis we can write

(a) v x – t relation:

As there is no term containing time, thus we can say that the horizontal component of velocity is time independent.

(b) v y – t relation:

From above relation we can say that the vertical component of velocity varies with linearly time, also
