What is the measure of the force of gravity on an object?
Force is the vector product of mass and acceleration: F = ma. Weight is a special case of that formula, where you substitute the acceleration of gravity, g, for a. We can thus write: W = mg.1
For instance, if an object has a mass of 10 slugs2, its weight near the surface of the Earth is 10 x 32.2 (ft/s2) = 322 pounds (pound-force). If an object has a mass of10 kilograms, its weight near the surface of the Earth is 10 x 9.8 (m/s2) = 98 newtons. You can calculate the force of gravity on an object (i.e., its weight) by putting it on a scale.
Lenz''s Law states that the Nature of induced emf in the coil is such that it opposes the causes of it. It can be explained by a simple understanding of Faraday EM induction ex
Q. Explain what is free fall acceleration? Answer:- On earth free drop acceleration is 9.81 meters per second per second or 32.2 feet per second per second not including a
Energy is transmitted in a plane in two mutually perpendicular directions. Example : Wave propagating on the surface of water.
NEGATIVE ACCELERATION OR RETARDATION OF DECLERATION: If velocity of a body is reducing, then its acceleration is said to be negative. The direction of negative acceleration is
