What is motion?
When the distance from another object is changing
|
What is speed
Distance an object travels per unit of time
|
What is acceleration.
The rate at which velocity changes.
|
|
What does milli mean?
The prefix that means thousandth
|
What is the formula for speed
Distance divided by time
|
What is the formula to find acceleration
Initial speed subtracted by final speed divided by time.
|
|
What does kilo mean?
The prefix that means thousand
|
What is velocity
Speed is a given direction
|
What is useful to analyze acceleration
Speed versus time and distance versus time graphs.
|
|
When can you tell if an object is in motion?
If an object changes position in relative to a reference point
|
What is slope on a graph and the equations used to find it
The steepness on a graph, you divide rise by run
|
What are three ways objects can acceleration
Decreasing, increasing speed, and changing direction.
|
|
Describe relative motion? Please use an example. (You don’t have to have to answer in a question for this one)
|
What is instantaneous speed
The rate at which an object is moving at a given rate of time.
|
What is 40m/s
