Unit B: Section 1.0 Flashcards
How can we tell if an object has moved?
We can analyze the motion of an object in comparison to another point
What is a reference point?
A point that we use to analyze the motion of an object
When does the motion of an object occur?
When an imaginary line attached to the reference point increases or decreases in distance or changes direction.
What is uniform motion?
When an object is traveling at constant rate of motion in a constant direction
What is average speed?
A uniform motion that involves traveling a distance in a specific time
What does the letter v mean in a mathematical formula?
Speed
What does a triangle mean before a letter in a chemical formula?
Difference in
What is the formula for average speed?
v = d/t or final distance - inital distance/ final distance - initial distance
What is the formula for slope?
Rise/run
Where does time go on a distance-time graph?
On the x-axis
Where does distance go on a distance-time graph?
The y-axis
What does a slope calculate in a distance-time graph?
Average speed
What does a straight line in a distance-time graph represent?
Uniform motion
What does a straight horizontal line on a speed-time graph represent?
As time goes the time goes on the speed remains constant
What does the slope of a speed-time graph confirm?
Whether or not the motion is uniform
How can you calculate the distance an object traveled on a speed-time graph?
By calculating the area underneath the graph
What is velocity?
The rate of motion and direction of an object
What is a scalar quantity?
A scalar quantity only represents the magnitude or how much and does not include direction
What is a vector quality?
A vector quality includes the magnitude or how much and a direction
How can you tell if something is a vector quality?
It will include an arrow overtop
What is distanced traveled?
A scalar quantity that measures the distance traveled by an object from a reference point
What is displacement?
a vector quantity the is a change in distance and direction from a reference point
What is the formula for average velocity?
displacement / time elapsed or
final distance - initial distance / final time - initial time
What does the slope represent on a position-time graph?
Velocity
