What does it take to prove a hypothesis false
It needs one counter example.
Which state of matter is air
Each value measured in nature has a number value called its magnitude and a dimension or
When can the equations of kinematics not be used
Equations of kinematics or equations of motion can not be used
when the body is not accelerating or is moving with a constant
A horizontal line on the velocity vs time graph indicates a constant positive acceleration
Which of the following is the name of the process scientists use to gain knowledge about the physical world
Speed is a vector quantity
It may help to know that a vector is a specific speed in a
specific direction. Example, 18kph at North Azimuth 84 degrees.
Which of the following is an example of an archery contestant showing good precision but poor accuracy
Missing the bulls-eye but hitting the same spot every time
For an archer to be precise but not accurate, they would be hitting very close to the same spot each time, but they would not hit the center of the target.
Which of the following settings describes a displacement vs time graph that looks like this
Zero acceleration and/or Moving object
Is the term used to describe the study of motion
The unit system used throughout most of the world is a metric system called the SI
Which of the following is not a key assumption to the scientific method
Distance is the magnitude of average velocity
Fred will be four blocks from his starting place if he travels two blocks north then three blocks east and then two blocks south Is it true or false
Which two of the following characteristics must a hypothesis possess in order to be considered to be scientific
A hypothesis must possess capable of being proven false and
testable in order to be considered to be scientific.
Are graphs representations of equations
Line graphs may represent equations, if they are defined for all
values of a variable.
What do you use To change from one SI prefix to another
Zeros are always considered significant digits when they are to the right of the decimal point and when they are between the decimal point and another digit as in 1304
All digits shown on the measuring device plus one estimated digit are consider
for short they are called "sig. figs."
What type of description is using numbers to describe kinematic quantities
Blank Is a process prompted by a question.
Giving an answer is likely the process that is prompted by a question.
Scientific must be testable and capable of being proven false.
