Quality is the measure of inertia an object, any object which is an inherent property of all. Suffered weight reflects the gravity of the size of the object, it is attracted by the Earth caused. 2. Quality is the scalar. Weight vector. ...
Example 1: The mass of the body is 50 kg. Calculate the weight using the weight formula. (Hint: use g = 9.8 m/s2.Solution: To find the weight of the body. Mass = 50 kg (given) Using the formula to find weight, W = mg W = 50 × 9.8 W = 490 N...

The most common definition of weight found in introductory physics textbooks defines weight asthe force exerted on a body by gravity. This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration. ...
You can think of weight as a function of an object's mass and the force, or acceleration, it experiences due to gravity.2 Mass is the measure of the amount of matter in a body. Mass is denoted using m or M. Weight is the measure of the amount offorceacting on a mass due to the...
