The attracting, pulling force between ALL objects with mass.
It's the force that keeps the Earth in orbit around the Sun. It's the force that keeps the Moon in orbit around the Earth.
Gravity

What is the (rearranged) equation to solve for mass?
m=(SigmaF)/a

If a 2 kg object has an acceleration of 15 m/s2, then what is the force associated (don't forget the units!)?
30 N!

What is Newton's First Law?
AP: You must include the extra details.
The Law of Inertia:
An object in motion will remain in motion (in a straight line at a constant velocity), and an object at rest will remain at rest, unless acted upon by a net force.

What is the equation form of Newton's Third Law?
F_(AB) = -F_(BA)

A thrust force of 500 N acts on a 1000 kg rocket. What is its acceleration?
0.5 m/s2
400
What do each of these forces represent?
Fa, Fg, FN, FT, FF
Fa = force applied
Fg = force of gravity (weight)
FN = normal force
FT = tension force
FF = force of friction

BLACKPINK fans are called this (a mash-up of “black” + “pink”).
BLINKs!

If all forces are balanced, this = 0.
In other words, if Fnet = 0, this variable also equals 0.
Acceleration
500
What are the 2 things the acceleration of an object depends on?
Net force acting on an object
Mass of the object

mass = 1,000 kg
acceleration = -9 m/s2
SigmaF_x=-9,000 N
