Click For Summary
Inertia is the phenomenon where objects with mass resist acceleration, and it is not attributed to a specific particle or force. Instead, it is influenced by factors such as energy, momentum, and stress, as described by the theory of relativity. The discussion touches on the concept of "inertialessness" from 1940s science fiction, questioning whether it's possible to nullify an object's inertia. However, current scientific understanding suggests that removing inertia is not feasible. Consequently, an inertialess object would not be able to exceed the speed of light.

Is there a specific particle or force that gives an object inertia? Going back to the 1940's science fiction ideas of "inertialessness", is there a way to nullify or remove an objects inertia? And if so, could an inertialess object go faster than light?

No; inertia is the name for the phenomena that objects with mass resist acceleration.
 
According to the theory of relativity everything related with energy, momentum, and stress contributes to inertia as well as gravity.

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
