"In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular arc."
Circular motion is any motion in which an object is moving along a circular path, whereas gravitation is the force of attraction between any two objects that have mass.
Newton's Laws of Motion: The three laws governing the motion of objects and their interactions with one another.
Centripetal Force: The inward force that keeps an object moving in a curved path.
Centrifugal Force: The outward force experienced by an object moving in a circular path.
Circular Motion: The motion of an object moving in a circle at a constant speed.
Kepler's Laws: A set of three laws that describe the motion of planets around a central star.
Gravitational Force: The force of attraction between two masses.
Universal Gravitation: The law that states that every object in the universe attracts every other object with a force that is proportional to their masses and inversely proportional to the square of their separation distance.
Gravitational Field: The area surrounding a massive object in which other objects experience a gravitational force.
Escape Velocity: The minimum velocity an object needs to escape the gravitational pull of a massive object.
Orbital Motion: The motion of an object in orbit around another object due to the gravitational force between them.
Geostationary Orbits: An orbit at a fixed position above Earth's equator, where the satellite appears to be stationary from Earth.
Simple Harmonic Motion: A motion that follows a periodic pattern, like a sine wave.
Conic Sections: The shapes resulting from the intersection of a plane with a cone, including circles, ellipses, parabolas, and hyperbolas.
Uniform circular motion: The motion of an object moving with constant speed along a circular path.
Non-uniform circular motion: The motion of an object that is moving along a circular path with varying speed.
Centripetal force: A force that inwardly pulls an object towards the center of the circular path, allowing it to maintain circular motion.
Centrifugal force: A fictitious force that outwardly pulls an object as a result of its circular motion.
Kepler's laws of planetary motion: Three laws that describe the motion of planets around the sun. These laws include the law of orbits, the law of equal areas, and the law of periods.
Gravitational force: The force that exists between two objects as a result of their masses. This force is directed towards each other.
Newton's law of universal gravitation: A fundamental law that describes the force of gravitation between two objects. It states that the force of gravity is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Gravitational potential energy: The energy that an object has as a result of its position in a gravitational field.
Escape velocity: The minimum velocity required for an object to break free from the gravitational pull of a planet.
Geostationary orbit: An orbit in which a satellite rotates at the same speed as the Earth's rotation, appearing stationary in the sky.
"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."
