 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
 nonbouncy 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
