Newton's Laws Quiz #1 Flashcards
force
a push or a pull
contact force
arises from physical contact
action-at-a-distance force (field force)
does not require contact and includes gravity/electric forces
mass
a measure of the amount of “stuff” contained in an object
force is a
vector
Newton’s 1st Law of motion (law of inertia)
an object at rest stays at rest, and an object in motion stays in motion
net force
the vector sum of all of the forces acting on an object
inertia
the natural tendency of an object to remain at rest or in motion at a constant speed along a straight line
The mass of an object is the
quantitative measure of inertia
Newton’s second law of motion
net force=mass x acceleartion
net force represents
backwards e, f
If an object is coming to a stop, the acceleration should be
negative
