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

Yes, according to the Motion in a Straight Line, for a moving object, the displacement can be zero, as it is the net change in position. It can also be defined as the shortest path between start and end points. If an object moves from a starting point and returns to the starting point, then the fina

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.

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

Under increasing load, the graphical representation showing the relationship between strain and stress for a given material is called the stress-strain curve. It provides the crucial information about the yield point (onset of payment deformation),  material's elastic limit, fracture point (poi
