- 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
