1) The bullet has a constant speed and travels in a straight line, so it will have a constant velocity and hence it is in uniform motion. 2)
Swinging pendulum
is under the action of gravitational force and is also changing its direction – hence it is not in uniform motion. It is non – uniform motion.
What is non-uniform circular motion?
Non-uniform circular motion denotes
a change in the speed of a particle moving along a circular path
.
Which is not a uniform circular motion?
In non-uniform circular motion an
object is moving in a circular path with a varying speed
. Since the speed is changing, there is tangential acceleration in addition to normal acceleration.
What is the example of non-uniform circular motion?
| Non-uniform Circular motion Uniform Circular motion | Example: Motion of a body on vertical circle, vertical circle with a string and bob, roller coaster, etc. Example: Motion of the Earth around the Sun, second, minute and hour hands of watch, motion of cyclists on a circular track etc. |

What is non-uniform circular motion class 9?
In non-uniform circular motion,
an object’s motion is along a circle, but the object’s speed is not constant
. In particular, the following will be true. The object’s velocity vector is always tangent to the circle. The speed and angular speed of the object are not constant.
What are the examples of uniform motion?
- The hr. …
- An airplane cruising at a level height and a steady speed.
- A car going along a straight level road at steady speed.
- A vibrating spring in a sewing machine.
- A ship steaming on a straight course at steady speed.
- A train going along the tracks at steady speed.
What is the acceleration toward the center of circular motion?
The centripetal acceleration a
c
has a magnitude equal to the square of the body’s speed v along the curve divided by the distance r from the centre of the circle to the moving body; that is,
a
c
= v
2
/r
. Centripetal acceleration has units of metre per second squared.
What is the example of non-uniform acceleration?
For example,
if a car travelling along a straight road increases its speed by unequal amounts in equal intervals of time
, then the car is said to be moving with non-uniform acceleration.
Is circular motion uniform?
In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It
can be uniform
, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
What are the two types of circular motion?
- Types of Circular Motion.
- There are two types of circular motion mentioned below:
- Uniform circular motion.
- Non-uniform circular motion.
- Uniform Circular Motion.
- When the motion of an object in a circle is at a constant speed, it is called uniform circular motion.
What is the formula for uniform circular motion?
| Equation Symbol breakdown | v = r ω v = r omega v=rω v v v is linear speed, r is radius, ω is angular speed. | T = 2 π ω = 1 f T = dfrac{2pi}{omega} = dfrac{1}{f} T=ω2π=f1 T T T is period, ω is angular speed, and f is frequency |

How can you apply uniform circular motion in your daily life?
- Amusement park ride.
- Satellites orbiting the Earth and our natural satellite Moon’s motion around the earth.
- Movement of a windmill.
- An athelete running on a circular track.
- Marry go round.
Is acceleration possible in uniform motion?
An object
undergoing uniform circular motion does not accelerate
. Why some people say it’s true: In uniform circular motion, speed remains constant.
What is mean by non-uniform speed?
Non-Uniform speed :
If a body covers unequal distances in equal intervals of time or equal distances in unequal intervals of time
,however small may be the intervals,is called Non -uniform velocity.
What is circular motion class 9?
The
movement of a body following a circular path
is called a circular motion. Now, the motion of a body moving with constant speed along a circular path is called Uniform Circular Motion. Here, the speed is constant but the velocity changes.
