FAQs on Uniform Speed and Non Uniform Speed - Motion & Time Video Lecture - Class 7
| 1. What is uniform speed in motion and time? |  |
Ans. Uniform speed refers to a situation where an object covers an equal distance in equal intervals of time. This means that the object is moving at a constant speed without any change in its motion.
| 2. What is non-uniform speed in motion and time? | |
Ans. Non-uniform speed is when an object covers unequal distances in equal intervals of time. This implies that the object is moving at a varying speed, either increasing or decreasing, during its motion.
| 3. How can we determine if an object is moving at uniform speed? | |
Ans. To determine if an object is moving at uniform speed, we need to measure the distance covered by the object in equal intervals of time. If the distance covered is the same for each interval, then the object is moving at uniform speed.
| 4. What are some examples of uniform speed in everyday life? | |
Ans. Some examples of uniform speed in everyday life include a car traveling on a highway at a constant speed, a ceiling fan rotating at a steady pace, or a cyclist maintaining a consistent speed on a straight road.
| 5. How is non-uniform speed different from variable speed? | |
Ans. Non-uniform speed and variable speed both involve changes in an object's speed. However, non-uniform speed specifically refers to speed that changes in unequal intervals of time, while variable speed can refer to changes in speed that occur at any time interval, whether equal or unequal.

uniform speed and non-uniform speed
observe the motion of the car displayed
here we observe that the car is covering
a distance of 10 meters in every one
second that is the car is moving with
uniform speed thus if a body covers
equal distances in equal intervals of
time irrespective of direction of motion
then it is said to be moving with
uniform speed in other words the body is
undergoing uniform motion when a body
moves with uniform speed then the total
distance traveled by the body in a
certain time interval is given by the
relationship distance traveled is equal
to uniform speed into time interval or s
is equal to V into T where s is the
distance travelled we is the uniform
speed and T is the time taken the
movements of the planets around the Sun
is uniform motion
non-uniform speed observe the motion of
the car displayed here we observe that
the car is covering unequal distances in
equal intervals of time that is the car
is moving with non-uniform speed or it
is undergoing non-uniform motion
now observe the rubber ball that is
dropped from a certain height when the
ball is dropped from a height onto the
floor it bounces off to a certain height
in subsequent bounces the height keeps
on decreasing here the ball does not
cover equal distances in equal intervals
of time that is the ball is moving with
non-uniform speed as if a body covers
unequal distances in equal intervals of
time or equal distances in unequal
intervals of time irrespective of
direction of motion then the body is
said to be moving with non-uniform speed
when a body travels with non-uniform
speed then the average speed of the body
is given by the formula average speed is
equal to total distance traveled by
total time taken
