"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 circular path.
Kinematics: The study of motion without considering its causes, including displacement, velocity, and acceleration of objects in circular motion.
Dynamics: The branch of mechanics that deals with the study of motion, force, and energy, including centripetal force, and angular acceleration.
Circular motion: Motion in a circle, including uniform circular motion and non-uniform circular motion.
Torque: A measure of rotational force, including the moment of inertia, angular momentum, and conservation of angular momentum.
Gravity: The force of attraction between two objects, including gravitational force and gravity in circular motion.
Oscillations: Motion that repeats itself over time, including simple harmonic motion, pendulum, and resonance.
Work and energy: The relationship between work done on an object and the energy transferred to it including kinetic energy, potential energy, and conservation of energy.
Equations of motion: Mathematical expressions that relate the motion of objects to their properties and interactions with the environment, including the equations of circular motion and the role of constraints.
Rotational kinematics: The study of circular motion of an object in terms of angular displacement, angular velocity, and angular acceleration.
Rotational dynamics: The study of the relationship between force and motion of an object in circular motion, including the moment of force, the principle of moments, and the conservation of angular momentum.
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 at a varying speed.
Simple Harmonic Motion: An oscillatory motion in which an object moves back and forth in a straight line with a continuous force acting towards the center of the motion.
Centrifugal Motion: A motion in which an object tends to move away from the center of the circular path.
Centripetal Motion: A motion in which an object tends to move towards the center of the circular path.
Conical Pendulum Motion: A type of motion in which a mass is suspended by a string and swings in a conical path.
Circular Orbit Motion: A motion in which an object orbits around a planet or a satellite in a circular path.
Planetary Motion: A motion in which a planet or a satellite orbits around the sun or a star in a circular or elliptical path.
Rolling Motion: A motion in which an object, such as a wheel, rolls along a surface in a circular or semi-circular 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."
