Newton’s laws of motion

Every object that undergoes a motion has momentum. The object’s mass and speed determine the momentum of the object. The law of conservation of momentum states that any object will have constant momentum before and after the motion. For example, when two bodies collide, the momentum before the collision is the same as the momentum […]

A physical quantity with both a magnitude and a direction is referred to as force. The ‘direction of force’ is the direction in which it is applied. A force is defined as a pull or a push on a body. The three laws of motion outlined in Isaac Newton’s Principia Mathematica are frequently used to

When a force is exerted on an item that remains constant across time, it is called a constant force. A constant force assists in maintaining an object’s constant speed and enables an object to move uniformly. Similarly, a force exerted on a stationary item is said to be continuous if it contributes to the object’s equilibrium

When we talk about instantaneous velocity, we are talking about the rate at which a point’s location changes during a very short period of time (i.e., less than one second) (almost zero). Metre per second (m/s) is the unit of measurement for speed. The instantaneous speed is the magnitude of the immediate velocity at the

In the world of physics, Sir Isaac Newton is the pioneer of classical physics with his laws of motion. The first law of Newton is also called the law of inertia. The law of inertia is the most important and recognized. In this article, let us discuss the first law of inertia in detail. Before

Introduction Inertia is the resistance by any object to move and to change in velocity, motion, and direction. Inertia is adapted from the Latin word ‘iners’ meaning idle.  Mass and inertia have a significant relationship.  Mass is the measure of inertia of a body. The inertia of any object will depend on this mass; the

Impulse Definition Impulse is a quantity which defines the effect of a net force acting on an object. A large force which acts for a short time to generate a finite change in the momentum is known as an impulsive force. Impulse Formula An impulse of a force is the change in momentum produced by

A vector, as we know, is any object that has both a direction and magnitude. Here we will learn about when two vectors are considered equal, what happens when a vector is multiplied with a number and what is called a unit vector. Equality of Vectors: If we want to talk about equality between two

When an object travels in a straight line and covers the same distance, and the velocity varies by different amounts, it is said that the object is in non-uniform motion. In other words, the rate of change in velocity is different at different time intervals. E.g., Consider the example of a kid playing with balls.

The law of elasticity was discovered by the scientist Robert Hooke in 1660. Hooke’s Law states that applied force is directly proportional to the spring constant and deformation of spring. Under the elastic limit, the object returns to its original shape and size when the load is removed from the object. Hooke’s Law is the
