Motion

A disturbance that travels through the space or medium transferring energy without the net movement of particles is called a wave. Rather than moving along with the wave, the particles of the medium only oscillate about their mean position in a wave motion. The wave is fundamentally different as com

Kepler's laws refer to the motion of planets around the Sun and it offers various insights into the celestial mechanics. It includes the following:

• The First Law (Law of Orbits) states that all planets move in elliptical orbits, and the Sun is at one focus. It is against the previous belief that plan

Rolling motion is a combination of rotational and translation motion where an object moves forward while spinning around an axis. An example is a rolling wheel. The equation for rolling motion without slipping is:

v represents the linear velocity, r is the radius and w stands for the angular velocity

Torque (? ) is used to measure the force that causes rotational motion. It is similar to how force causes linear motion. Newton's second law for rotational motion shows the relation between torque and angular acceleration.

I stand for the moment of inertia and a is the angular acceleration. According

Moment of Inertia (I) is the rotational equivalent of mass and it is used to measure an object's resistance to changes in its rotational motion. I is based on the mass of the object and how it is distributed relative to the axis of rotation. The formula to measure the moment of inertia is -

Translational motion is when every part of an object moves at the same speed and uniformly in the same direction, like a car moving along a straight road. Rotational motion refers to an object rotating around a fixed axis, eg- a spinning wheel. One of the main difference is that in translation motio

The centre of mass (COM) of a system refers to the point that represents the average position where the entire mass of the system is considered to be concentrated. The concept helps in analyzing the motion of a system of particles. Following is the formula to determine the COM of two or more particl

To master the Class 11 Physics Chapter 3 Motion in A Plane numerical problems, students need to focus on key concepts like kinematic equations, vectors, uniform circular motion and projectile motion. Develop a strong understanding of vector resolution to break forces into components. Other things th

The scalar and vector quantities are different in terms of direction. Scalars have only magnitude and no direction. It follows basic arithmetic operations for addition and subtraction. Examples of scalar quantities include speed, time, mass and temperature. On the other hand, the vectors have both m
