Velocity / Time Graphs Flashcards
1
Q
What does a horizontal line on a velocity / time graph represent ?
A
A=v-u. 5
—- = —- = 1m/s squared
T. 5
2
Q
What does an upward sloping line represent
A
It represents a positive acceleration ( increasing velocity )
3
Q
What does a downward slope represent ?
A
A negative acceleration ( a deceleration, or a decrease in velocity )
4
Q
What is the equation for calculating the distance travelled from speed (or velocity ) and time
A
Distance = speed x time
Area = length x width
Area of a triangle = base x height x half
5
Q
Explain why you don’t need to carry out any calculations to work out the acceleration in stinks b,g,d
A
Those sections of graph are horizontal which means that the acceleration is zero
