[Channel-talkforce] inertia definition

From: Still, Ruth <rstill@hershey.k12.pa.us>

As a physics teacher, shouldn't inertia be defined a little differently than what was described in the 2nd video? In this video, they described it as...
        "an object at rest tends to stay at rest".....but inertia also includes objects in constant straight line motion. Doesn't this confuse the kids later when they go on to the next levels of science?

Thanks,
Ruth STill
