what is
who made the 3 laws of motion
issac newton
inertia
first law
what is applied force
a force that is applied to an object by a person or another object.
what is net force
the sum of all the forces acting on an object
what is non contact force
the pull or push an object without it touching the object
newtons third law
for every action there is an equal and opposite reaction
rocket engines ignite pushing glasses down and the thrust that is generated pushed the rocket up
3rd law
what can force do
how do you solve for net force
F = ma
what is the unit of force
newtons first law
law of interia
forces are equal but opposite
3rd law
what is contact force
force between touching objects
Can a stationary object have a net force?
no
how does non contact force affect objects
a pulls or push them away if they are strong enough without them touching
newtons 2nd law
law of acceleration
the higher the mass the lower the acceleration
2nd law
what is an example of contact force?
frictional force
applied force
normal force
true or false
if an object is not accelerating, it does not have a net force applied to it
true
is gravitonal force contact or non contact
non contact
what is Net force
the sum of all the forces acting on an object.
a person pulling a wagon stops and the wagon moves forward hitting the person
1st law
when you are pushing something heavy and it requires more ____
Frictional force
When two forces act on an object in opposite directions, how should you calculate the net force?
do you need friction for a non contact force
no because friction requires one thing pushing another while touching
