Re: Drive by science
Exactly that!
You can think of inertial mass (to distinguish it from anything involving gravity or parameters in a particle theory) as a measure of how much something resists being pushed off its current course. If something is sat still, its mass indicates how much force you'd need to apply to get it to accelerate away from that force. A low mass is easy to make accelerate; a high mass much harder.
If you have a negative mass, then it measures just the opposite: how much force you need to apply to get it to accelerate toward that force.
