We’ve all fantasized about riding a horse while wearing a nice cowboy hat and performing the lasso trick. The lasso trick is a superb illustration of a physical motion in and of itself. A lasso trick is, in fact, a famous illustration of circulatory motion. The continual circular motion of the hand keeps the rope moving and keeps it from dropping to the floor. Let’s take a closer look at circular motion.
What is Circular Motion?
- Circular motion’s definition says that this is the motion of an object along a circular route while spinning.
- Also, unlike linear motion, the direction of motion changes continuously in the case of the circular motion of a body.
- As a result, angular variables can be used to characterize circular motion.
- The angular variable in a circular motion is as:
- It’s the angle at which a rotating object turns in one unit of time.
- Theta (𝜃) is the symbol for it, and it is expressed in radians.
- It’s the rate at which a particle’s angular displacement changes in a circular motion.
- The unit of angular velocity is rad/s.
- A particle in circular motion has linear velocity and matching linear speed in addition to angular velocity and angular speed.
- It is defined as the rate at which the rotating particle’s angular velocity changes.
- It is expressed in rad/s2.
The common circular motion formulas are
ω = lim∆t→0 (∆θ/∆t) = dθ/dt ,
α = dω/dt = d2θ/dt2,
ar = V2/R
Where ω is the angular velocity,
t is the time, θ is angular displacement,
α is the angular acceleration,
ar is the angular acceleration,
V is the velocity and
R is the radius of the motion.
Types of Circular Motion
Circular motion can be of two types: uniform or non-uniform circular motion.
- The angular rate of rotation and speed are constant in uniform circular motion, whereas the rate of rotation changes in non-uniform motion.
- The velocity vector changes direction at every point on the curve during circular motion. As a result, the radial component of acceleration is never zero.
- In the event of non-uniform circular motion, the tangential component might be positive or negative, and in the case of a uniform circular motion, it can be zero.
Movement of a giant wheel, satellites orbiting around earth and the motion of a merry-go-round are some of the circular motion examples.
- The motion of an object along a circular route while spinning is called circular Motion.
- Angular variables like angular displacement, angular velocity and angular acceleration can be used to characterize circular motion.
- Circular motion can be of two types: uniform or non-uniform circular motion.
