Yogita Ingle 6 years ago

Impulse is the big force acting for a very small interval of time. It is represented by J⃗ J→.

Impulse Formula is articulated as

J= F × t

Where,

Force applied is given as F
Time interval throughout which force is applied is given as t.

Gravitational Constant: Cavendish experiment

Cavendish performed an experiment to calculate the value of G.
To calculate the value of G he took a wooden plank and attached two 2 balls on either side of the plank and hung this with a thin thread from the top.
He introduced 2 very big balls and those balls are near the smaller balls.
He observed that the small balls got attracted to big balls and wooden plank started rotating and as a result the thin thread started twisting.
This happened because of force of attraction between the small balls and bigger balls.
He observed that :-

Plank rotates till twisting force becomes equal to the gravitational force between the balls.

? = G m₁m₂/r²

LƟ = G m₁m₂/r²

By using the above equation he calculated the value of G,

G= 6.67x10^-11Nm²/kg²
Units of G : Nm²/kg²
