CP1B Distance/Time graphs Flashcards
Give an equation relatinghg average speed, distance and time
average speed(m/s) = distance (m)
—————–
time taken (s)
On a distance/time graph, what value does the gradient of the line represent
The speed
On a displacement/time graph, what value does the gradient of the line represent
The velocity
What must be done to calculate speed at a give time from a distance-time graph for an accelerating object
Draw a tangent to the curve at the required time
Calculate the gradient of the tangent
What does a horizontal line represent
Object is stationary
What does a straight sloping line represent
The object is travelling at a constant speed
What happens the steep the line gets
The faster the object is travelling
State a typical value for the speed of sound
330 m/s
What is the typical value of human walking speed
1.5 m/s
What is the typical value for human runnning speed
3 m/s
What is the typical value for human cycling speed
6 m/s
