A detailed guide to properties of dot product

Class 11, Kinematics, Motion in a plane: Vector quantities, projectile motion, NEET, Physics

In Physics, terms like force, velocity, speed, and work are classified as scalar or vector quantities. Scalar quantities are physical quantities with magnitude and no sense of direction. Vectors consist of both magnitude and direction. Therefore, operations such as addition and multiplication can be easily performed on them. Multiplication, in particular, can be done in […]

A Brief Note on Coplanar Vector

Class 11, Kinematics, Motion in a plane: Vector quantities, projectile motion, NEET, Physics

Physicists use a wide variety of mathematical quantities. These words include acceleration, velocity, speed, force, work, and power. These different numbers are often referred to as “scalar” and “vector.” Vectors are a type of geometric entity with magnitude and direction. Vectors have a starting point and a terminal point that represents the point’s final position.

Unit of Force

Class 11, Kinematics, NEET, Physics, Uniform and non-uniform motion

Force A push or pull on an object that occurs as a result of the object’s interaction with another object is referred to as force. Any physical quantity can now be represented by its dimensions. Force=mass×acceleration The dimensional formula of force can be given: Effects of Force Changes in the position of the body To

Pulley

Class 11, Kinematics, NEET, Physics, Uniform and non-uniform motion

A pulley is a wheel with a flexible rope, cord, cable, chain, or belt attached to the rim. Pulleys are used to transport energy and motion, either alone or in combination. Sheaves are rimmed pulleys with grooves. Pulley We come across several machines in our daily lives that we sometimes fail to notice them. One

Coulomb’s Law for Forces Between Multiple Charges

Class 11, Kinematics, NEET, Physics, Uniform and non-uniform motion

Since Ancient Egypt, specialists have utilized specific instruments to perform intrusive systems. Since the beginning of time, new careful strategies have co-developed with novel careful instruments. By and large, a specialist expects apparatuses to cut open and access tissues, suture kit (cutting, analyzation and withdrawal instruments), control dying (hemostasis instruments), and physical rebuilding and careful

Conservative Force

Class 11, Kinematics, NEET, Physics, Uniform and non-uniform motion

In Newtonian mechanics, the two most crucial entities that we need to consider are force and work. These two entities walk hand in hand because work is done whenever a force will act upon an object and displace it. Similarly, if work has happened, a force has been applied. Force can be of many types

Average Speed

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, Physics

Introduction Speed is the total distance travelled by an object in unit time, whereas velocity is the total displacement travelled by the object in unit time. You must already know about speed and velocity and the different types of properties that both of them possess. Now, we are going to learn about average speed and

Average Speed and Velocity

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, Physics

Before we can learn about average speed or average velocity, it is important to understand the difference between distance and displacement. Distance is a scalar quantity that indicates how much ground the object has covered. However, displacement on the other hand is a vector quantity. It is the shortest distance between the end and the start

Work Done by Spring

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, Physics

A spring exerts a force against the force we apply while extending the spring to attain an equilibrium position. Every spring has its stiffness, known by the spring constant (k). Springs with large spring constants are stiff and are difficult to compress. According to Newton’s Third Law of Motion, when force is applied to the

Velocity-time and Position-time Graphs

Class 11, Kinematics, Motion in a straight line: Distance, displacement, velocity, NEET, Physics

The velocity of an object is the rate of change of position of any particle with respect to a frame of reference. Velocity is a function of time. Velocity-time graph is representation of variation of velocity of any moving object with respect to time. Velocity-time graphs are also called speed-time graphs. The vertical axis of
