Distance refers to the total length of the path traveled by an object, regardless of its direction. It is a scalar quantity, meaning it only has magnitude (size) and no direction. Distance is always positive and cannot decrease as an object moves, because it represents the cumulative length of the path covered. Key Points: Example:
For JEE Main + Advanced Physics and Board Exams In kinematics, motion refers to the change in position of an object over time. It describes how objects move, but not why they move (which is the focus of dynamics). Kinematics studies motion in terms of displacement, velocity, and acceleration, without considering the forces causing the …
The human eye functions similarly to a camera and uses lenses to focus light and form images. Here’s a detailed explanation suitable for Class 10 Physics:Structure and Functioning of the Human Eye The human eye is a complex organ that allows us to see by refracting light rays and forming images. Here’s how it works: …

Refraction of light by spherical lenses is an essential concept in optics for Class 10 NCERT. Spherical lenses are transparent materials with at least one curved surface that cause light rays to bend or refract. They are primarily categorized into two types: Basic Terminology Refraction in Convex Lenses Convex lenses are thicker at the center …
Reflection of light by curved surfaces, particularly mirrors, is an important concept in optics. For Class 10 NCERT, it’s essential to understand how light interacts with concave and convex mirrors. Here’s a detailed explanation: Curved Mirrors Curved mirrors can be of two types: Basic Terms Reflection in Concave Mirrors For concave mirrors, the behavior of …

In the context of Class 10th ICSE (Indian Certificate of Secondary Education) Board, the concept of turning forces refers to the principles of rotational equilibrium and the factors affecting the turning or rotational motion of an object. It’s also commonly known as the concept of moments or torque. Understanding turning forces is essential not only …
Observation Table for Experiment here’s a simple experiment to investigate the factors affecting the period of a simple pendulum. A simple pendulum consists of a mass (called the bob) attached to a string or rod of fixed length. Title: Factors Affecting the Period of a Simple Pendulum Objective: To investigate how the period of a …
Series Circuit: In a series circuit, resistances add up. The total resistance (RtotalRtotal) is the sum of individual resistances. Rtotal=R1+R2+R3+… Example: Suppose you have three resistors with resistances R1=5 ΩR1=5Ω, R2=3 ΩR2=3Ω, and R3=2 ΩR3=2Ω connected in series. The total resistance (RtotalRtotal) would be: Rtotal=5 Ω+3 Ω+2 Ω=10 Ω Parallel Circuit: In a parallel circuit, the reciprocal of the total resistance (Rtotal−1Rtotal−1) …

Ohm’s Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. It is named after the German physicist Georg Simon Ohm, who first formulated it. Ohm’s Law is expressed by the equation: V=I⋅R where: This equation indicates that the …
Projectile motion refers to the motion of an object that is thrown or projected into the air and is subject to the force of gravity. The key characteristic of projectile motion is that the object follows a curved path, known as a trajectory, rather than a straight line. This type of motion is a result …
