The coefficient of restitution e for a perfectly elastic collision is

An elastic collision is a type of collision where both momentum and kinetic energy are conserved. During this interaction, objects may deform temporarily but return to their original shapes afterward. Examples include collisions between billiard balls or gas molecules, demonstrating ...

Two identical balls A and B collide head on elastically. If velocities of A and B, before the collision are +0.5 m/s and -0.3 m/s respectively, then their velocities, after the collision, are respectively

An elastic collision is one in which both momentum and kinetic energy are conserved. During the collision, the objects may deform momentarily but return to their original shapes without loss of energy. Examples include collisions between billiard balls or gas ...

Write an expression for torque in three-dimensional motion. Hence write the expressions for the rectangular components of torque.

Three-dimensional motion involves movement in three spatial dimensions, characterized by changes in position along the x, y, and z axes simultaneously. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

Show that the magnitude of torque = magnitude of force x moment arm. Also show that only the angular component of the force is responsible for producing torque.

Magnitude refers to the size or amount of a quantity, regardless of its direction, often used to describe scalar and vector quantities. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
