Question

the 2kg mass and 10 kg mass objects are moving with the same velocity i.e 10m/sec. which one has more inertia.

Answer 1

Explanation:

the object with 10 kg mass will have more inertia

Answer 2

Answer:

Explanation:

Given , Mass of object  ,m=10 kg

Velocity of object , v=20ms  

−1

 

Initial Kinetic energy , K

​  

=20 kg

Final Velocity , v

​  

=10m/s

Final Kinetic energy , K
