Let l be the moment of inertia of a uniform square plate about an axis AB that passes through its centre and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the centre of the plate and makes an angle θ with AB. The moment of inertia of the plate about the axis CD is then equal to

Inertia is the tendency of an object to resist changes in its state of motion or rest, depending on mass. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

A ball hits the floor and rebounds after an inelastic collision. In this case

In an inelastic collision, objects collide and stick together, losing some kinetic energy, though momentum is conserved throughout the interaction. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

Write an expression for the kinetic energy of a body rolling without slipping.

Kinetic energy is the energy possessed by an object due to its motion, calculated as half the mass times velocity squared. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

A light string is wound round a cylinder and carries a mass tied to it at the free end. When the mass is released, calculate (a) the linear acceleration of the descending mass and (b) the angular acceleration of the cylinder and (c) the tension in the string. Show that the acceleration of mass is less than g.

Acceleration is the rate of change of velocity of an object over time, indicating how quickly it speeds up or slows down. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
