newtons laws
An object in motion stays in motion unless...
acted upon by an outside force
all objects have
inertia
weight is a measurement of...
the gravitational force on an object
G is a
constant
p=
momentum
F=
ma
The smaller the mass the less force needed therefore less...
Inertia is used
to find body weight
mass times free-fall acceleration
all objects in the universe attract each other through
the force of gravity
m=
mass
An action has an...
equal and opposite reaction
Inertia definition
The tendency of an object to resist a change in motion unless an outside force acts upon an object
mass never...
changes
state that force increases if one/both masses...
increase or distances decreases
v=
velovity
Newtons first law is called
The law of inertia
Newtons second law is...
unbalanced forces acting on an object equals the objects mass times its acceleration
weight changes because
((m1m2)/d2
f=g
p=
mv
Inertia needs to have what
needs to have a net force
1N=
0.225lbs
f=
g
force can be looked at in.
2 ways
will increase if
mass or velo increases
