Hint- To answer the nature of speed and velocity in uniform linear motion. We will use the concept that when the distance travelled by a moving body is the same at several time intervals, regardless of the time length.
Complete step by step solution:
In uniform linear motion the distance and displacement are equal at every particular time interval. Therefore the speed and velocity at every particular time interval are equal. So we can say that in uniform linear motion the speed and velocity are constant.
Hence the option A is the correct answer. Which is that speed and velocity will remain constant in uniform linear motion.
Additional Information-
Moves along a straight line with a constant speed.
Same displacement in equal time intervals of time, however small the intervals be.
Same as the actual speed or velocity of the body.
Uniform linear motion is the motion in which acceleration is zero. Both the direction and magnitude of the velocity remains constant in uniform linear motion, hence it is not an accelerated motion. Either there is no external force applied or the net force applied on the is zero.
In uniform motion the paths under the graphs are straight line(vertical, horizontal or slanting).
Note- This result can also be verified by plotting a graph. The distance time graph shows a straight line in case of uniform linear motion.
