A particle of mass m moving with velocity v collides with a stationary particle of mass 2 m. After collision, the speed of the combined particle is

Collisions occur when two or more bodies come into contact, resulting in an exchange of momentum and energy. They can be elastic, where kinetic energy is conserved, or inelastic, where kinetic energy is not conserved. Understanding collisions is essential in ...

A body moves a distance 0f 10 m along a straight line under the action of a 5 N force. If the work done is 25 J, then angle between the force and direction of motion of the body is

The direction of motion refers to the path along which an object moves. It is determined by the object’s velocity vector, indicating both speed and the angle at which it travels. Understanding the direction of motion is essential in analyzing ...

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

Two point masses of 0.3 kg and 0.7 kg are fixed at the ends of a rod of length 1.4 m and of negligible mass. The rod is set rotating about an axis perpendicular to its length with a uniform angular speed. The point on the rod through which the axis should pass in order that the work required for rotation of the rod is minimum is located at a distance of

Rotation is the circular movement of an object around an axis, where every point in the object moves in a circular path. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
