How do Newton’s
laws impact our
everyday lives?

Why do objects at a
constant velocity remain
at that velocity?

Sources: 18

Claim: The objects will only remain
at that constant velocity if an outside
force doesn’t act against it. And that
is exactly why it remains at a constant
velocity, nothing is stopping it

Evidence: Its like cruise control,
It keeps going until an outside
force stops it, such as the brakes.
The brakes will stop the cruise
control and the car too.

Inertia: a property of matter by
which it continues in its existing
state of rest or uniform motion in
a straight line, unless that state
is changed by an external force

Inertia is the “reason” that the
velocity stays constant.

Personal Experience: I was riding a
scooter at a campground when i was
like 10 and i rode it down a steep hill
and couldn’t stop in so once i got
in the grass i fell off, it's kind of the
same thing

In which direction will
an object move if acted
on by multiple forces?

Sources: 20

Claim: It will simply go the way
the greater force is applied.

Evidence: -------------> [] ←------
30N 15N
It will go ----> with 15 N of force

If you are playing tug of war the only way
you can win is but pulling more than the other side.

A push and a pull are both forces and when
you are adding to the net force.

Mass doesn’t really relate to acceleration in
the formula aspect but it does if you’re trying
to find the amount of force being applied.

Acceleration formula: A = Vf - Vi / Time

Personal Experience: My brother and I
were pushing a four wheeler when it ran
out of gas, he was on it and that is sort
of and opposite force pushing against me
pushing it because it is making it heavier
and making there be more friction

How can two objects of
different sizes exert the
same amount of force
on each other?

Sources: 21, 22

Claim: The smaller one must
put more force into it because he
has less momentum just because
he weighs less. The bigger one has
more weight so even with a little
speed he gains much more force than
a smaller person.

The other part of the third laws is if
you apply force to something you will
feel the force you put in back on yourself.

Evidence: Momentum: the quantity of motion
of a moving body, measured as a product of
its mass and velocity
Momentum formula: P=mv
(momentum= mass x velocity)

If a person weighs 100 kg and is going 10 m/s
it would have to same force as a person that weighs
1000 kg and is going 1 m/s or a person that weighs
10kg going 100 m/s .

The weight doesn’t really matter, only thing that
matters is the end force, when you multiply weight
and speed.

If you hit something and your hand hurts it's
because you feel the force you hit with back onto
your hand.

Personal Experience: It's kind of like a treadmill,
it spins which makes you have to run faster so you
don’t fall off. You running is like your force and the
treadmill spinning is its force and you are “pushing”
against it by running.

I seen someone hit a wall and their knuckles start
bleeding because they feel the force they hit the
wall with.

Final answer:They impact our lives because without them we wouldn’t understand how/why balls roll and how they stop, we wouldn’t understand why things fall like they do, everything would just happen and there would be no explanation.

Initial Answer:They affect pretty much everything that moves and are based off what we assume to happen to objects when they are move
