Has string theory changed the practice (if it actually was the practice) of describing particles with equations of behaviors instead of as actual objects (like points or maybe strings).
Mass refers to the amount of matter in a particle, while weight refers to the force of gravity acting on the particle. Mass is a constant property, while weight can vary depending on the gravitational pull of a particular location.
The mechanical descriptions of particles are based on Newton's laws of motion, which describe the relationship between an object's mass, acceleration, and the forces acting upon it. These laws help us understand and predict the behavior of particles in motion.
Velocity and acceleration are important parameters in mechanical descriptions of particles as they determine the motion of the particle. Velocity refers to the rate of change of an object's position, while acceleration refers to the rate of change of its velocity. These values help us calculate the trajectory and speed of a particle.
Forces are measured using a unit called Newtons (N) in mechanical descriptions of particles. A force is a push or pull that can cause an object to accelerate or change direction. The magnitude of a force is determined by the mass and acceleration of the particle.
Yes, mechanical descriptions of particles can be applied to systems with multiple particles. The laws of motion and principles of mechanics can be used to analyze the behavior and interactions of multiple particles in a system, such as in a gas or fluid.
