True or False Physics is the basic scirnce
TRUE
What is the language of science
Math
The sceientific method steps in order are
1. reconize a problem
2. Make a hypothesis
3. predict the cosequences f the hypothesis
4. preform the experiemnt
5. formulate the simplest general rule
True or False a scientist ALWAYS follows a dogma
FALSE
technology
is applied science,
speed
measure of how fast something is moving
average speed
averaged speed=total distance covered/time
velocity
speed with direction
accleration
change in velocity(speed)/time
vector qwuanity
direction and speed
scaler
speed
newton's first law of inertia is also known as...
the law of intertia
inertia
an objects resistance to change in strgait constant linear movement
Every object continues in a state of rest or a state of motion in a straight line at a constant speed, unless it is compeeled to change that states by foreces exerted upon it.
law of inertia( or Newton's first law)
True or false mass is also a measure of inertia
TRUe
9.8="g"
true
9.8= a newton
true
net force
sum of all forces acting on an object
Newton's second law of motion
the accleration produced by a net force on an object is directly porportonal to the magnitude of the net force, is in the same direction of the net force, and is inversly proptional to the mass of the object
Newton's third law of motion
Whenever one object exerts a force on a second object the second object exerta an equal and opposite force on the first object. (for everything thre is a equal and opposite reaction)
How many laws dose Newton have
3
impluse=
force X time (f(t)
impluse also is
change in momentum
elastic collision
bouncy collision
inelastic collision
non-bouncy collison
net mometnum(before collision)=net momentum(after collison) true or false
true! conservation of energy says so
work =
force times distance
kinetic engery =
1/2 mass X speed squared
conservation of energey
energery is neither created nor destoryed it is conserved and transformed
true or false centrifugal fotrce keeps you in your vare when you make a turn
FALSE! centripital force does
torque =
force times lever arm
in order for something to balance the clockwise and counterclock wise force have to be equal, true or false
true
resistance=
(formula)
voltage/current
current=
(formula)
voltage/resistance
