What is mass also state it’s si unit,symbol and what it is measured with |
Mass is amount of matter in an object Si unit is kilogram (kg) Symbol is m Measures with beam balance or electronic balance |
|
|
What is weight also state it’s symbol,si unit,what it is measured with |
Weight is the force with which earth attracts a body to its centre Symbol w Si unit newton(N) Measured with spring balance |
|
|
Formula of weight |
W=mg m is mass(kg) g is gravitational field strength(fixed value and si unit is N/kg) Hence kg cancels with kg and weight=Newton |

What is density also state it’s symbol,units and formula |
Defined as mass per unit volume d or p(rho) Si units: kg/m^3 or g/cm^3 d=m/v |
|
|
How to find density of liquid |
1-mass of measuring cylinder m2-m1(empty cylinder-with liquid) 2-read volume from cylinder 3-d=m/v |
|
|
How to find density of a solid |
1-Mass if solid by placing on balance 2-if regular shaped,measure volume using dimensions(lxbxh) and if irregular shaped,use displacement method(v2-v1) 3-d=m/v |
