A car on a race track travels around the circular
track at a constant speed. Is it in equilibrium?

Suppose you are in an elevator as it accelerates
upwards. At that moment, you would feel
________. Why is this?
Heavier than normal This is because as the
elevator accelerates upwards, you lag behind (due
to your inertia), so you feel pressed against the
floor harder. Thus, its your reaction to the
floor pushing you upward that makes you feel
heavier than normal.

A 1-N apple sits on the surface of the Earth.
What is the Earths weight in reference to this
apple? (Note that Im not asking for the Earths
mass!)
1 Newton
The Earths weight depends on the object youre
measuring it against. So since the Earth pulls
on the apple with a force of 1-N, the apple pulls
back
on the Earth gravitationally with a force of 1-N.
