Velocity & distance time graphs Flashcards
What is velocity of an object
The speed in a patricular direction
Gradient =
Speed
What does the flat section mean on a velocity and distance time graph? _______________
- its stationary
- its stopped
What does the gradient represent on a distance time graph
The spped of the object
What does the straight uphill or down hill section mean on a velocity and distance time graph
\ /
Means its travelling at
-steady speed
True or false for distance time graph
the steeper the graph the slower it goes
False
-the steeper the graph the faster its going
True or false for distance time graph
- down hill sections means its going back to the starting point
True
-downhill sections mean that its going back to the starting point
True or false for distance time graph
-curves represent acleration or declerartion
True
-curves do represent accleration ir decleration
true or false for distance time graph
-A steepening curve means its slowing down
false
- A steepening curve means its speeding up
- (increasing gradient)
true or false for distance time graph
-a levelling off curve means its slowing down
true
- a leveling off curve means its slowing down
- (decreasing gradient)
what are speed and velocity measured in ?
m/s
what is speed ?
speed is -how fast your going and direction is not needed
what is velocity ?
velocity is -how fast but must have direction specified
give an example of velocity
give an example of speed
velocity -40mph north or 2m/s 060
what is the formula for speed
-speed = distance -:-time
