Laws of Motion

In General the Linear momentum is the product of mass and velocity of a system. In equation form it is represented as: p = mv. We can see from the calculation that the force is directly proportional to the mass of the object (m) and the velocity (v). Therefore, the larger the object mass, the […]

In astronomy and physics, Kepler’s laws of planetary motion tell us about the motions of the planets in the solar system. These laws were discovered by the German astronomer Johannes Kepler. He analysed the observations of the 16th-century astronomer Tycho Brahe and published his first two laws in 1609. The third law was derived nearly

Momentum  Momentum is a physical quantity associated with the object (system of particles). It is defined as time required to bring any object in motion to rest by applying constant force to it.  How to calculate Momentum of a system of particles? Mathematically, momentum (P) of any particle is the product of its mass and

Many well-known scientists speculate that there might be one formula to define all the laws and phenomena of physics. Why? Because almost every law, principle, theory, and observation made of the physical world shares some similarities. This similarity is observed as being analogous. In simple words, analogous means similar in comparison. In physics, comparisons can

Before Galileo Galilei found the concept of the moment of inertia, scientists believed that an external force is required to move a body, keep it in motion, and stop a body. They thought that a body stops as soon as the force applied to it is withdrawn. For example, if we are rowing a boat,

Instantaneous velocity, sometimes known as just velocity, is the number that informs us how quickly an item is travelling somewhere along its route. If two places on a path are separated by a significant amount of time (and hence by a large amount of distance), this is the average velocity between them. It is necessary

Any object which is thrown into space and the only force acting upon it is gravity is called to be projectile, and the motion which the body undergoes is called projectile motion. The path undertaken by the projectile is known as trajectory.   We tend to assume that the object is near the surface of the

All objects in the universe are in one or more non-inertial frames of reference. These frames of reference are separated from inertial frames of reference by a variable in which the speed of light is constant. This means that an object is moving at a different speed in a non-inertial frame of reference than it

In physics, quantities such as velocity and displacement change based on the observer’s point of view or the frame of reference from which the values are observed. Any point in space can be represented in the form of its cartesian coordinates like (x,y,z), where x is the distance of that point from the x-axis on

In Physics, force, velocity, speed, and work are usually classified as scalar or vector quantities. Scalar quantities only have magnitude but no direction. Vectors consist of both magnitude and direction. A quantity that depends on the magnitude and direction like force, displacement, momentum, velocity, and acceleration is known as the vector quantity. It is denoted
