Laws of Motion

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

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
