Study Of Motion Ugh Flashcards
vELOCITY SUM
Velocity = displacement
—————
time
What is acceleration ??
The rate of Change of velocity
What unit is used for velocity
m/s2
Sum for acceleration
A= finalspeed-initialspeed
———————–
time taken
What do straight lines show on a distance time graph?
A steady constant speed/velocity
What does steepness show on a distance time graph?
Shallow = low speed Steep = high speed
What do horizontal lines show on a distance time graph?
Stationary
What does a curve show on a distance time graph?
Acceleration/deceleration
What axis is time on in both velocity time graphs and distance time graphs
X
The bottom one
What do straight diagonal lines show on a velocity time graph?
Steady acceleration / deceleration
What does steepness show on a velocity time graph?
Shallow = smaller acceleration Steep = larger acceleration
What does a horizontal line show on a velocity time graph?
Speed is constant
How can you calculate the distance from these graphs
The area of space below the lines, eg triangle = 1/2 base x height
