Below, the person in the train (on

frictionless rollerblades) is in

a non-inertial reference frame

They will think that all

sorts of crazy

forces are at work that

don’t really exist

because they are trying

to apply Newton’s Laws

incorrectly

You and I

know better

because we can

view the situation

from an inertial

reference frame

“thrown backwards”

“thrown forwards”

“thrown outwards”

The fictitious forces, experienced

by our friend in the train, are in quotes
