what are constrains in Physics
Answers
Answer:
A constrained motion is a motion which cannot proceed arbitrarily in any manner.Particle motion can be restricted to occur (1) along with some specified path (2) on the surface (plane or curved) arbitrarily oriented in space.Imposing constraints on a mechanical system is done to simplify the mathematical description of the system.Constraints expressed in the form of equation f(x1,y1,z1,……,xn,yn,zn:t)=0" role="presentation" style="box-sizing: inherit; display: inline-block; line-height: 0; text-indent: 0px; text-align: left; text-transform: none; font-style: normal; font-weight: normal; font-size: 19.62px; letter-spacing: normal; word-wrap: normal; word-spacing: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; margin: 0px; padding: 1px 0px; position: relative;">f(x1,y1,z1,……,xn,yn,zn:t)=0f(x1,y1,z1,……,xn,yn,zn:t)=0are called holonomic constraints.Constraints not expressed in this fashion are called non-holonomic constraints.
Answer:
In classical mechanics, a constraint on a system is a parameter that the system must obey.
For example, a box sliding down a slope must remain on the slope.
