Examples of circular motion are carousels or merry-go-rounds in parks, a car going around a roundabout, the moon orbiting around the Earth or the Earth revolving around the Sun.

What is circular motion question answer?
The motion of an object along a circular path is called circular motion. It is of two types: uniform circular motion and non-uniform circular motion. The motion of a body moving with constant speed along a circular path is called uniform circular motion.
How do you solve a circular motion question?
What is circular motion 12th physics?
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 10 examples of circular motion?
- Planets Revolving Around the Sun.
- Giant Wheel.
- Satellites Orbiting Around Planets.
- Stone Tied to a String.
- Stirring Batter.
- Running on a Circular Track.
- Merry-Go-Round.
- Movement of Electrons Around Nucleus.
How many types of circular motion are there?
There are two types of circular motion mentioned below: Uniform circular motion. Non-uniform circular motion.
What is Ke formula?
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
How do u calculate force?
Force exerted by an object equals mass times acceleration of that object: F = m * a .
What is the formula for circular velocity?
The circular velocity vC = (ฮผ/r)1/2, is the speed of a body in a circular orbit at a distance a = r from the primary.
What is a circular motion called?
Angular Acceleration The motion is called uniform circular motion when the particle is moving along a circular path possessing a constant speed. During circular motion, the velocity vector changes its direction at each point on the circle.
Why is circular motion important?
Circular motion is very common and very important in our everyday life. Satellites, the moon, the solar system and stars in galaxies all rotate in “circular” orbits. The term circular here is being used loosely since even repetitive closed motion is generally not a perfect circle.
What keeps the object moving in circular path?
A centripetal force is a net force that acts on an object to keep it moving along a circular path.
What are 5 types of forces?
- Muscular Forces. Muscles functions to produce a resulting force which is known as ‘muscular force’.
- Frictional Forces. When an object changes its state motion, ‘frictional force’ acts upon.
- Applied Force.
- Tension Force.
- Spring Force.
- Gravitational Force.
What is the SI unit of acceleration?
The SI unit of acceleration is metres/second2 (m/s2).
Why is UCM called periodic motion?
Solution : In a uniform circular motion (UCM), a particle takes the same time to complete each revolution, a distance equal to the circumference of the circle. Therefore, a UCM is called a periodic motion.
Is clock a circular motion?
Since any point on the hand of the clock moves in a circular direction, they are said to be in circular motion. It is also periodic as it repeats its motion .
What is the characteristic of circular motion?
A particle in uniform circular motion is identified by two characteristics: It is moving at a constant speed v and is moving in a circular path with a radius r. Then the acceleration of the particle is directed radially toward the center of the circular path and has magnitude v2/r.
What are the types of motion?
According to the nature of the movement, motion is classified into three types as follows: Linear Motion. Rotary Motion. Oscillatory Motion.
Which force is required for circular motion?
The force required for circular motion is centripetal force.
Is circular motion non uniform?
The circular motion can be uniform if the angular rate of rotation and speed are constant. The motion can be non-uniform if the angular rate of rotation is varying with time. An electron moving perpendicular to the magnetic field is an example of circular motion.
What force causes centripetal motion?
Centripetal forces cause centripetal accelerations. In the special case of the Earth’s circular motion around the Sun โ or any satellite’s circular motion around any celestial body โ the centripetal force causing the motion is the result of the gravitational attraction between them.
What are 4 types of kinetic energy?
- Mechanical Energy. Mechanical energy is the energy that we can see.
- Electrical Energy. Electrical energy is better known as electricity.
- Light Energy (or Radiant Energy)
- Thermal Energy.
- Sound Energy.
What is the unit velocity?
Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.
Is velocity a speed?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
What are the 3 formulas for force?
- a = v/t.
- F = mv/t.
- F = p/t = dp/dt.
