Question

Sanjay says that if he throws/flings the Frisbee disk with greater speed it will have a greater inertia. Rahul argues that inertia does not depend on speed, but rather upon mass. why do you agree with? explain why?



plz help me​

Answer 1

Rahul is correct , Inertia is dependent on only mass.

Detailed discussion:

• First of all, what is Inertia ?

• Inertia is the ability of a body to stay in motion or at rest until and unless disturbed by a force.

• Inertia is extensively described in NEWTON'S 1ST LAW OF MOTION.

• Now, inertia is such a property which is directly proportional to the mass of the object.

• Inertia $\propto$ Mass

• Putting simply, higher the mass of the object higher will be the inertia.

So, throwing the frisbee at higher velocity doesn't mean that it will have higher inertia (so Sanjay is wrong) , rather if the frisbee is made more heavy, it will have more inertia.
