Conservative forces (like gravity or spring force) conserve mechanical energy and do not depend on the path taken. The work done by the conservative forces is recoverable.
Non-conservative forces (like friction or air resistance) dissipate energy as heat or sound. It depends on the path. When non-con

Energy is measured in joules (J). It is the capacity to do work while power is the rate of using energy or doing work. Power is measured in watts (W). One watt equals one joule per second. Power talks about how fast the work is done, and energy is about how much work is possible. 

When without slipping a body rotates and translates simultaneously is called rolling motion, such as a wheel on a road. It is the combination of rotatory and translatory motion. The point of contact has zero velocity relative to the surface in pure rolling. It is a condition in which there is no sli

According to the Class 11 Physics Chapter 6 System of Particles and Rotational Motion, for a rigid body to be in complete equilibrium, two conditions should be met:

• Net external torque = 0 (rotational equilibrium)
• Net external force = 0 (translational equilibrium)

The condition for equilibrium in rotat

The moment of inertia of a body about any axis to its moment of inertia about a parallel axis through the center of mass is the parallel axis theorem.
It states:
I = Ic + Mh2
Ic is the moment of inertia about the center
I is the moment of inertia of the body
h2 is the square of the distance between the t

To master the Class 11 Physics Chapter 3 Motion In A Plane, the students need to focus on thoroughly understanding vectors, and practice problems involving circular motion and projectile, for clarity, students should draw diagrams. They should memorize the key formulas, solve NCERT examples and atte

When an object moves in two dimensions, vectors help in representing quantities like velocity, acceleration, and displacement. They allow easy subtraction, addition, and resolution into components. It helps in simplifying the analysis of complex motions like circular motion, projectiles, and motion

When an object moves around a circular path at a constant speed, it is called the uniform circular motion. The velocity changes while the speed remains constant because its direction keeps on changing. The centripetal acceleration is responsible for this change, which is directed towards the center

The relative velocity is an object's velocity which may itself be in a motion as observed from a particular frame of reference. In a straight line (one dimension) if object A has velocity vA and object B has velocity vB, then the velocity of object B relative to object A (vBA) is given by vBA=vB? vA

The scalar quantities are physical quantities with no direction and only magnitude (size). Examples of scalar quantities are mass, temperature, speed and distance. On the other hand, vector quantities have both magnitude and direction. The examples are force, acceleration, displacement and velocity.
