particle at rest
In physics, a particle at rest refers to a particle that is not moving or in a state of motionlessness
In physics, a particle at rest refers to a particle that is not moving or in a state of motionlessness. When a particle is at rest, its position remains constant over time. It has zero velocity, meaning its speed is zero and it is not changing its position.
Particles can be at rest in various contexts, such as in classical mechanics, where objects on a surface are at rest in reference to that surface, or in quantum mechanics, where particles can be at rest in their energy eigenstates.
The concept of a particle at rest is important in physics as it serves as a reference point for studying and analyzing the motion and behavior of other particles. By understanding how particles behave when they are at rest, scientists can then observe and measure changes in motion and velocity.
