what is newtons 1st law
what is newtons first law
A OBJECT IN MOTION STAYS IN MOTION UNLESS ACTED ON A OUTSIDE FORCE
what is newton's second's law of motion
Force equals mass multiplied by acceleration
what is newton's 3rd law of motion
for every action, there is a equal and opposite reaction
what if a car is speeding faster and faster what is that balanced or unbalanced
unbalanced
what is friction
the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
what is a net force
The sum of all the forces acting on an object.
what's the formula of this law
force = mass x acceleration
For every action force there exists an equal and _____ reaction force.
opposite
what is a balanced force
a force that is balanced is when to forces don't change
the friction on a cars tires or necessary or unwanted
necessary
What is Inertia
the natural tendency of an object to resist changes in its state of motion
the _______ the force, the greater the acceleration
greater
Forces always comes in ______
pairs
what is a unbalance force
an unbalanced force is when two forces have the different masses
The sum of all the forces acting on an object.
surface area, force pushing objects together, surface roughness
What do external forces do?
change the motion
if there is a box that weighs 10 grams and a another one that was 5 which one is lighter
5 grams cause it has less mass
For every action force there exists an equal and _____ reaction force.
opposite
balanced or unbalanced: a motorcycle that is going at a constant speed
balanced
is friction in a car engine necessary or unwanted
unwanted
A non-zero net force will change the _____.
velocity
if a car weights 150 pounds and there is same car that weights 150.1 which one weights more
the second car is 150.1 pounds
A rocket engine expels hot exhaust gases downward out of its nozzle what happens
the rocket will go up cause the gases push the rocket down
balanced or unbalanced: a bike leaning on a tree
balanced
if a ball is kicked on a straight road and it stops why does it happen
it stops because of friction
