JEE

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. 

Candidates scoring good ranks must go for JEE Advanced exam. If not, then they must should focus on improving their JEE Main score to get into CCSU by taking multiple mock tests and practicing previous year's question papers. Candidates can identify their areas of proficiency and topics where they n

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

All students need a very strong fundamental knowledge of concepts, formulas and problems variations, which can be only achived through the NCERT textbooks. that is why our NCERT Solutions for Class 11 Three-Dimensional Geometry are a very relaible resource to build strong basics with accuratre infor

Dear,

you can't got any NIT/IIIT with this rank 

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.

Distance and displacement both refer to how far an object has moved, but the meanings are different. The distance is a scalar quantity and it is the total length covered by an object, irrespective of the direction. It is always positive, and talks about how much ground the object has covered. On the

Motion in a straight line is used to describe an object's movement along a straight line in a single direction. It is also known as the rectilinear motion. In Motion in a Straight Line, the position of the object changes along one dimension and unless an external force is applied, its direction stay
