No, weight is due to gravity, so always acts vertically, and movement is not a force.faen said:
A particle on a circle refers to a physical system where a point particle moves along the circumference of a circle under the influence of a force.
Newton's Law for a particle on a circle states that the sum of the forces acting on the particle must be equal to its mass multiplied by its acceleration in the tangential direction.
To solve for the motion of a particle on a circle using Newton's Law, you must first identify all the forces acting on the particle, including the centripetal force. Then, you can use Newton's Second Law to set up an equation and solve for the acceleration. Finally, you can integrate the acceleration to find the particle's position and velocity as a function of time.
The centripetal force is the force that acts towards the center of the circle, keeping the particle in its circular motion. It is equal to the mass of the particle multiplied by its tangential acceleration.
Particle on a circle problems can be found in many real-life scenarios, such as the motion of planets around the sun, the motion of a car around a circular track, and the motion of a rollercoaster on a loop. They are also commonly used in physics experiments and simulations to understand and analyze circular motion.
