Explain Centripetal force??
Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pulling the body absent of line. When the force acts on the body from a fixed point, like a body moves in a circle, and the force towards the centre is known as a centripetal force.
Michelson-Morley experiment (A.A. Michelson, E.W. Morley; 1887) Probably the most popular null-experiment of all time, designed to check the presence of the proposed "lumenife
Derive an expression for the torque acting on a loop of N turns, area A, carrying current i, when held in a uniform magnetic field. With the help of ciruit, show how a moving coil
what difference between these two laws
Draw a free-body diagram for the space shuttle just after it leaves the ground. Recognize the forces acting on the shuttle. Make sure that you do not neglect air resistance.
pascal; Pa The derived SI unit of pressure explained as 1 N working over an area of 1 m 2 ; thus it has units of N/m 2
The weight of a body is the force with which it is attracted in the direction of the centre of earth. When an object is stationary with respect to the planet, its weight equivalent
michelson interferometer principle
Unbalanced forces cause accelerations. In this case, the unbalanced force is directed opposite the book's motion and will cause it to slow down. To verify if the forces acting
brewsters law
Q. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
