When a body moves along a straight line, then the product of the, mass m and the linear velocity of the body is called the “linear momentum” p of the body (p = m*v), if a body is rotating about an axis, then the sum of the moments of the linear momenta of all the Read more about Relation between Angular Momentum and Moment of inertia[…]
Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown near the earth’s surface, and it moves along a curved path under the action of gravity only.Motion along Horizontal direction: A body projected from the ground with a velocity u at an angel with the horizontal. Horizontal components of the velocity Read more about Projectile motion[…]
This law states that pressure in a fluid in equilibrium is the same everywhere, if the effect of gravity can be neglected. Proof: We can show that pressures at any two points C and D in a liquid in equilibrium state of rest in a vessel are the same. Let us imagine a right circular Read more about Pascal’s Law[…]
Let us consider a parallel-faced slab whose cross-sectional area is A and length L. Let its faces be maintained at steady temperatures θ1 and θ2. Heat will flow through the slab from the face at higher temperature θ1 to that at the lower temperature θ2. Let us assume that no heat escapes out from the Read more about One-dimensional Flow of Heat: Coefficient of Thermal Conductivity[…]
NEWTON’S FIRST LAW OF MOTION: Everybody continues to be in a state of rest or uniform motion in a straight line, except in so far as it be compelled by an externally impressed force to act otherwise.INERTIA: It is the inherent property of a body, by virtue of which, the body cannot change its state Read more about Newton’s Law of Motion[…]
Every particle in this universe attracts every other particle with a force that is proportional to the product of these masses and inversely proportional to the square of the distance between them.Thus, F = Gm₁m₂/r², where and are the gravitational masses of the particles, r is the separation between them and G is Universal Gravitational Read more about NEWTON’S LAW OF UNIVERSAL GRAVITATION[…]
According to Newton’s law of cooling the rate of loss of heat, dQ/dt of the body is directly proportional to the different of temperature ΔT = (T2 – T1) of the body and the surroundings. The law holds good only for small difference of temperature. Also the loss of heat by radiation depends upon the Read more about Newton’s law of Cooling[…]
The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.According to newton’s 2nd law, the rate of change Read more about Law of conservation of momentum[…]
Energy is either created or destroyed but converts from one form to another.At point A: A body of mass ‘m’ is thrown up with a velocity ‘u’ from the ground level. Let us take the point as A. therefore it has only kinetic energy and potential energy is equal to ‘0’ at A. Energy at A Read more about Law of conservation of energy[…]
Kepler’s first law or law of orbits: It states “all the planets moves around the sun in an elliptical orbit with sun at one of the focus of ellipse”. The point when the planet is nearest to the sun is termed as point when the planet is nearest to the sun is termed as perihelion and Read more about KEPLER’S LAWS[…]
