Speed vs. Velocity
Distance vs. Displacement
100
What Is the velocity of this graph?
10 m/s
100
If the line on a position-time graph is linear, what is happening to the object? (Hint: Is moving at a _______ __________)
the object is moving at a constant speed
100
A vector has both _________ and ________.
Magnitude and direction
100
What is the term for how fast an object is moving without considering its direction
speed
100
What is the distance of this graph
60
200
What Is the speed of this graph?
10 m/s
200
if the line on a position time graph is flat what is happening to the object?
the object is not moving
200
A scalar quantity has ____________
Magnitude
200
What is the term that describes the speed of an object and the direction its moving
velocity
200
What is the displacement of this graph?
0
300
What is the Speed of this graph?
3 m/s
300
If the line on a position-time graph is positive linear, which direction is the object moving?
Away
300
Is a vector the same thing as velocity?
No, but velocity is a quantity of a vector!
300
What is the key difference between the speed and velocity
velocity includes direction while speed does not
300
What is the definition of distance on a graph?
The distance is the WHOLE route, or every foot step taken.
400
What is the Velocity of this graph?
3 m/s
400
If the line on a position-time graph is negative linear, which direction is the object moving?
Towards
400
Is a scalar the same thing as direction?
No, in fact it isn't even a quantity of a scalar.
400
If an object changes direction but keeps the same speed what happens to its velocity
velocity changes because the direction changes
400
What is the definition of displacement?
Final position minus initial position
500
Does this graph have a stopping point?
No
500
How do you get the velocity of an object form a position-time graph?
Slope
500
What is an example of a scalar?
Volume, density, speed, energy, mass, and time.
500
if an object is not moving what is its velocity
zero
500
Why are distance and displacement so different?
Distance is the whole thing, and displacement is how far away you are from where you started
