What is the formula for average speed?
Total Distance / Total Time.
What is the formula for average velocity?
Total Displacement / Total Time.
Define acceleration?
is the rate of change of velocity.
What does instantaneous acceleration mean?
is the acceleration at a specific moment in time.
What does the slope of a displacement-time graph represent?
The slope of a (answer) graph represents velocity.
What does the slope of a velocity-time graph represent?
The slope of a (answer) graph represents acceleration.
What does a horizontal/flat line on a velocity-time graph indicate?
A horizontal line indicates constant velocity
What does the area under a velocity-time graph represent?
The area under the graph represents displacement.
What does a horizontal/flat line on an acceleration-time graph indicate?
A horizontal line indicates constant acceleration.
What is instantaneous speed?
is the speed of an object at a specific moment in time.
What is the difference between distance and displacement?
Distance is the total path length, while displacement is the straight-line change in position.
What does a straight line on a displacement-time graph indicate?
A straight line indicates constant velocity.
What does a curved line on a displacement-time graph indicate?
A curved line indicates changing velocity (acceleration).
What are scalar quantities?
(answer) quantities have only magnitude and no direction.
List 3 scalar quantities.
Distance
Speed
Time.
What is speed?
Speed is how fast an object is moving, without considering its direction.
What are vector quantities?
(answer) quantities have both magnitude and direction.
What is displacement?
(answer) is the straight-line distance between an object’s starting and ending points, along with the direction.
What is velocity?
(answer) is the rate of change of displacement, including direction.
What is the difference between average speed and average velocity?
Average speed is total distance divided by total time (scalar), while average velocity is total displacement divided by total time (vector).
List 3 vector quantities.
Displacement
Velocity
Acceleration.
What is distance?
Distance is the total length of the path traveled, regardless of direction.
What is the formula for average acceleration?
Average Acceleration = Δv / Δt.
