"In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular arc."
Deals with the motion of objects that travel in a circular path.
Angular displacement: The angle through which a body rotates in a given time.
Angular velocity: The rate of change of angular displacement with time.
Angular acceleration: The rate of change of angular velocity with time.
Tangential velocity: The linear velocity of a body moving in a circular path.
Centripetal acceleration: The acceleration that acts towards the center of the circular path.
Centripetal force: The force required to keep an object moving in a circular path.
Uniform circular motion: The motion of a body moving in a circular path with a constant speed.
Non-uniform circular motion: The motion of a body moving in a circular path with a changing speed.
Momentum in circular motion: The momentum of a body in circular motion.
Torque in circular motion: The force that causes rotation in circular motion.
Work in circular motion: The energy required to perform work in circular motion.
Power in circular motion: The rate at which work is done in circular motion.
Moment of inertia: A measure of the resistance of a body to rotation.
Rotational kinetic energy: The energy possessed by a rotating body.
Kepler's laws of planetary motion: Three laws describing the motion of planets around the sun.
Conservation of angular momentum: The principle that the angular momentum of a system remains constant if there are no external torques acting on it.
Coriolis force: The apparent force that acts on a moving object due to the rotation of Earth.
Simple harmonic motion: The repetitive motion of an object back and forth through its equilibrium position.
Pendulum motion: The motion of an object that swings back and forth under the influence of gravity.
Gyroscope motion: The motion of a spinning object that maintains its axis of rotation in a fixed direction.
Uniform circular motion: This occurs when an object moves in a circular path at a constant speed, such as a satellite in orbit around Earth.
Non-uniform circular motion: This occurs when an object moves in a circular path at a varying speed, such as a car traveling around a racetrack.
Centripetal motion: The motion of an object towards the center of a circular path due to a centripetal force acting on it, such as a car turning a tight corner.
Tangential motion: The motion of an object along a tangent to a circular path, such as a ball being thrown horizontally from a spinning merry-go-round.
Simple harmonic motion: The back-and-forth motion of an object along a straight line, such as a pendulum swinging back and forth under the influence of gravity.
Conical pendulum motion: The motion of a pendulum swinging in a conical path, such as a yo-yo being swung around in a circle.
Planetary motion: The motion of planets and other celestial bodies in elliptical orbits around a central star, such as the planets in our solar system.
Rotational motion: The motion of an object around an axis, such as a spinning top or a turning wheel.
Orbital motion: The motion of an object in orbit around another object, such as a moon orbiting a planet.
Galilean transformation: The conversion of motion between a stationary observer and a moving observer, such as the apparent motion of the stars as seen from a moving car.
"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."
