Scientific Method
the starting point of any scientific investigation
What is an observation?
the base unit of lenght
What is the meter?
the total length of the path that is taken
What is distance?
an object's speed averaged over a given period of time
What is average speed?
rise over run
What is slope?
detailed scientific explanation for a set of observations
What is the hypothesis?
the base unit of time
What is the second?
the change in an object's position
What is displacement?
an object's displacement per unit of time
What is average velocity?
A negative tilting of a straight line
What is a negative slope?
the value you change in an experiment
What is the independent variable?
the base unit of mass
What is the kilogram?
T/F - distance and displacement are equal
What is false?
name two characteristics of speed
What are: rate of motion, always positive, the greater the speed, the faster it moves
A forward tilting straight line
What is a positive slope?
the value you measure in an experiment
What is the dependent variable?
the measure of gravitational force acting on an object
What is weight?
the equation for displacement
What is delta x = xf -xi?
Name two characteristics of velocity
What are: both rate of motion and direction, sign (+/-) gives direction, the magnitude of V is the speed of motion
the line on a graph crosses over the axis
What is the intercept?
a logical interpretation of your observations
What is an inference?
a type of calculation written in terms of dimensions
What is dimensional analysis?
a frame of reference
What is a coordinate system?
Give the SI units for velocity
What is m/s?
the steeper the slope
What is the greater the average speed?
