Newton’s laws of motion

Multiplication of vectors is an important tool in many fields of physics, including distance, energies, forces, work done, electric or magnetic fields, and many more applications.  Multiplication of any vector with a real number is known as scalar multiplication. This multiplication alters the magnitude of the vector but does not disturb its direction. However, if […]

Introduction When an object changes its position in accordance with its surroundings with time, it is called motion. Motion is basically a change in the position of an object over a period of time. Motion in a straight line is a linear motion.  The main aspects of motion in a straight line is mentioned during this course

Introduction Motion is common to several things that move around us. Falling leaves, walking, running all have motion common in them. Also, our earth is in motion though we don’t feel it. Motion can be in a straight line (1D), in a plane (2D), or space (3D). The motion of an object in one direction

In physics, motion is the change in position or orientation of a body over time. Translation refers to a movement along a straight line or a curved path. Rotation is defined as movement that alters the orientation of a body. All places in the body have the same velocity (directed speed) and acceleration in both

Momentum is defined as the tendency of a body to keep moving in the same direction unless an external force acts on the body. Momentum is basically the multiplication of the mass and velocity of the body. Momentum has both magnitude as well as direction hence it is a vector quantity. It means momentum has

Linear motion is motion in one dimension. It is the most basic form of motion. It is when motion is along one line. Different paths describe different linear motions. Uniform linear motion is when the velocity is constant, or acceleration is zero. Non-uniform linear motion is when the velocity is not constant, or acceleration does

Aristotle was the first to propose that a body must be propelled by an external force. He neglected to consider that an opposing frictional force acts on the body to counteract the external force, resulting in a net force of zero on the body.Inertia is the basic property of all bodies that prevents them from

The essence of all current physics theories is Newton’s equations of motion.This article discusses momentum and how it can be conserved. A moving object’s momentum is defined as the product of its mass and velocity. It is a vector quantity that can be measured in kilogram-metre per second. The direction of a body’s momentum is

When two or more bodies are acting upon each other, the complete momentum is said to be constant unless an external force is applied. This is known as the law of conservation of linear momentum. So, the momentum can neither be created nor destroyed. In other words, between the two objects, the total momentum which

Newton’s first law states that when a particle is in equilibrium, the total of the forces acting on it is zero. If a particle in equilibrium is subjected to only three coplanar, concurrent and non collinear forces, the vectors representing the three forces have a specific geometry, which is described by Lami’s theorem. Lami’s theorem
