Today in class, we learned about Newton's first three laws
of Physics.
1: An object at rest will stay at rest and an object in
motion will stay in motion unless acted upon by an outside, unbalanced force.
2: Force equals mass times acceleration.
3: If two bodies exert force on each other, the two objects
will move with the same magnitude, yet in the opposite direction.
In order to learn and understand Newton's first law of
physics, we recreated the tablecloth trick where you pull the paper out from
under the pen super fast so the pen stays standing. This works as well with
rugs and furniture. At home, I tried to pull the rug out from under a chair but
it was super easy to keep the chair standing. This got me wondering – I know
all objects that are at rest will tend to stay at rest, but is the amount of
force needed to bring an object to motion after its been at rest based oan its
mass?
