Physical quantities which need both magnitude and direction to be fully expressed are called vector quantities. Displacement, velocity, acceleration, force, electric intensity etc are the examples of vector quantities. A vector quantity is a physical quantity that has both magnitude and direction. This means that in order to fully describe a vector quantity, you need … Read more
Understand the concept of instantaneous speed, its difference from average speed, and how to calculate it using real-world examples. What is instantaneous speed? A Complete Guide How fast an object is moving at a particular moment is the measurement of Instantaneous speed. Instantaneous speed is a scalar quantity. Instantaneous speed refers to the speed of a … Read more
The rate of change of velocity with time that is the change of velocity in unit time is known as acceleration.
The point with respect to which the displacement of an object is measured is called reference point.
The rate of increase of velocity of a freely falling body on earth due to force of gravity is called acceleration due to gravity. The Earth pulls you down, keeps your feet firmly planted on the ground, and makes a dropped apple hurtle toward the ground. This invisible force, ever-present but often taken for granted, … Read more
The rate of change of velocity with the time that is the change of velocity in unit time is known as acceleration. In the realm of physics, acceleration stands as a fundamental concept that governs the motion of objects. It describes the rate at which an object’s velocity changes over time. This change can manifest … Read more
The difference between one division of vernier scale and one division of the main scale is called the vernier constant. People’s Choice
By coiling a wire, the magnetic field intensity will be increased. Due to the flow of the current through the coil, most of the lines of the force will be concentrated in the centre of the coil. This type of coil is called solenoid. A solenoid is a type of electromagnet that consists of a … Read more
