Answer:
hey mate here is ur answer
a. uniform velocity
b. non uniform velocity
c. non uniform velocity
d. uniform velocity
hope it helps u
mark me as brainlist
follow me
a) a stone thrown vertically up => non uniform velocity
b) light travels through vacuum => uniform velocity
c) a ball rolled up on a floor => non uniform velocity
d) motion of minute hand of a clock => uniform velocity
When a body covers equal distances in equal intervals of time (however small may be the time interval) in a specified direction, the body is laid to be moving with uniform velocity.
Example: A car moving on a straight road with constant speed has uniform velocity.
When an object covers unequal distances in equal intervals of time in a specified direction. If the direction of motion changes, it is said to be moving with a non-uniform or variable velocity.
e.g., a revolving fan at a constant speed has variable velocity.
