"In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular arc."
The motion of an object along a curved path. It involves concepts such as centripetal force, tangential velocity, and radial acceleration.
Angular displacement: The angle through which an object has rotated from its initial position.
Angular velocity: The rate of change of angular displacement with respect to time.
Angular acceleration: The rate of change of angular velocity with respect to time.
Centripetal force: The force required to keep an object moving in a circular or curved path.
Centripetal acceleration: The acceleration experienced by an object moving in a circular path. It is always directed towards the center of the circle.
Tangential velocity: The velocity of an object moving along the tangent to the circle at any point.
Coriolis force: The apparent force that appears to act on objects moving in a rotating reference frame.
Kepler's laws of planetary motion: Three laws that describe the motion of planets around the sun.
Conservation of angular momentum: The principle that states that the angular momentum of an object will remain constant in the absence of an external torque.
Gravity and circular motion: The effect of gravity on objects moving in circular paths.
Uniform circular motion: The motion of an object at a constant speed in a circular path.
Non-uniform circular motion: The motion of an object at a changing speed in a circular path.
Rigid body dynamics: The study of the motion of bodies that maintain a constant shape and have a fixed orientation.
Rotational kinetic energy: The energy possessed by an object due to its rotation.
Elastic collision in circular motion: The collision between two objects in circular motion where the total kinetic energy is conserved.
Inelastic collision in circular motion: The collision between two objects in circular motion where the total kinetic energy is not conserved.
Rolling motion: The motion of an object that is simultaneously rotating and translating.
Torque: The force that causes an object to rotate or turn about an axis.
Coriolis effect: The apparent deflection of a moving object away from its original path when viewed from a rotating reference frame.
Centrifugal force: The apparent force that appears to push outwards on objects moving in a circular path.
Uniform circular motion: An object moves in a circular path at a constant speed.
Non-uniform circular motion: An object moves in a circular path, but its speed changes.
Simple harmonic motion: An object moves back and forth in a circular path, with the motion being driven by a restoring force.
Cycloidal motion: An object moves in a path that is a cycloid, which is a specific mathematical curve.
Torsional oscillation: An object moves in a circular path while experiencing a twisting force.
Planetary motion: A special type of circular motion in which planets orbit around a star due to the gravitational force.
Circular motion with friction: An object moves in a circular path, but frictional forces act on it, reducing its speed.
Precession: A phenomenon in which the orientation of an object's axis of rotation changes while rotating in a circular path.
Geostrophic motion: Circular motion of air or water around a low or high-pressure system due to the Coriolis effect.
Foucault pendulum motion: A pendulum suspended from a fixed point moves in a circular path due to the Earth's rotation.
Lissajous figures: A pattern created by the oscillation of two pendulums moving independently in circular motion.
Gyroscopic motion: The motion of an object rotating about an axis while maintaining its orientation due to gyroscopic properties.
Spiral motion: A type of circular motion in which an object follows a spiral path, getting closer or further from the center of the circle.
Epicyclic motion: A type of circular motion in which an orbiting object also rotates about its own axis, creating a complex path.
"It can be uniform, with a constant rate of rotation and constant tangential speed, or non-uniform with a changing rate of rotation."
"The rotation around a fixed axis of a three-dimensional body involves the circular motion of its parts."
"The equations of motion describe the movement of the center of mass of a body, which remains at a constant distance from the axis of rotation."
"In circular motion, the distance between the body and a fixed point on its surface remains the same, i.e., the body is assumed rigid."
"Examples of circular motion include: special satellite orbits around the Earth (circular orbits), a ceiling fan's blades rotating around a hub, a stone that is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a mechanism."
"Since the object's velocity vector is constantly changing direction, the moving object is undergoing acceleration by a centripetal force in the direction of the center of rotation."
"Without this acceleration, the object would move in a straight line, according to Newton's laws of motion."
"Circular motion is when an object moves along the edge of a circle or rotates around a curved path."
"The constant distance between the body and a fixed point on its surface ensures that the body is assumed rigid during circular motion."
"The rotation around a fixed axis of a three-dimensional body involves the circular motion of its parts."
"Special satellite orbits around the Earth exhibit circular motion as they consistently move along the circumference of the orbit."
"A ceiling fan's blades rotating around a hub is an example of circular motion, where the blades move along the circular path."
"A stone tied to a rope and being swung in circles demonstrates circular motion, where the stone moves along a curved path."
"When a car turns through a curve in a race track, circular motion is involved as the car follows a curved path."
"An electron moving perpendicular to a uniform magnetic field experiences circular motion, where its path forms a curve."
"A gear turning inside a mechanism exhibits circular motion as it rotates along a circular path."
"Circular motion involves a constantly changing direction of the object's velocity vector, unlike straight-line motion."
"The equations of motion describe how the center of mass of a body moves at a constant distance from the axis of rotation."
"Without the centripetal force that causes acceleration, the object in circular motion would follow a straight line, as explained by Newton's laws of motion."
