Answer 1

Answer:

1:Inertia in a moving bus when brake is applied

Similarly, the passenger tends to fall back when the bus accelerates from rest because when the bus accelerates, the inertia of the rest of the passenger tends to oppose the forward motion of the bus. Hence, the passenger tends to fall back when the bus accelerates forward.

2:mass

The physical quantity that measures the inertia of a body is its mass. More the mass of an object, more will be its inertia

Answer 2

$\boxed{\rm{\red{Question:\longrightarrow }}}$

why do we fall backwards when a bus accelerates from rest?

$\boxed{\rm{\blue{Answer:\longrightarrow }}}$

When a bus starts suddenly from rest , We fall backwards because of Inertia of Rest of us. This is due to the fact that because of their inertia , We tends to remain in their state of rest when the bus starts suddenly...

$\boxed{\rm{\orange{Question:\longrightarrow }}}$

Name the physical quantity that measures inertia and Write it's S.I unit also..?

$\boxed{\rm{\green{Answer:\longrightarrow }}}$

The physical quantity that measures the inertia of a body is it's mass. More the mass of an object, more will be it's inertia. and the S.I Unit of Mass is Kilograms (Kg)..
