Welcome to wonderful physics world!

Let me tell you how to determine ‘g’

Made by Lucifer who comes from AS3Tutor: RamRam

Method 1g=weight/mass

Weight ( newton meter or spring balance ) Mass ( common balance )

We can use 2 balances to work out mass

a) b)

Method 2

• T=2π(l/g)^1/2(use rule to measure)

• G=4π^2l/t^2 (use stop watch to measure)

Method 3 • Dropping stone or watch

Stone

Fall down

Duct ion equipment

0： 00

Methods 4

• Ticker timer

• Use a ticker timer to catch the wake of the object

Ticker timer

Tongs the power source or supply

paper tape

object

Method 5

• Light-gater ( sensor)

• In a dark room , we can use light-gater to catch the wake too

Method 6

• Data loggers

• We can also use data loggers to determine g .

Hi I am Lucifer!Thank you for your

reading.I hope I can get a

high marks.
