# Additional physics-Velocity and distance time graphs

?
What is speed and velocity?
1 of 15
What is this measured in?
m/s
2 of 15
What is the difference between speed and velocity?
Speed is how fast your going with no regard of direction and velocity is with what direction your going
3 of 15
Whats the formula for speed?
distance divide by time =speed
4 of 15
what doe the gradient of distance time graph tell you?
How fast your object is travelling
5 of 15
Why is this?
Because the gradient is the change in the distance (vertical axis)divided by the change in time (horizontal axis)
6 of 15
speed
7 of 15
What do flat sections on distance time graph mean?
stationery-its stopped
8 of 15
Straight uphill or downhill sections mean?
9 of 15
The steeper the graph?
the faster its going
10 of 15
Downhill sections mean?
its going back towards its starting point
11 of 15
Curves represent?
acceleration or deceleration
12 of 15
The steepening curve means?
its speeding up and increases gradient on the graph
13 of 15
Levelling off curve means?
Its slowly slowing down (decreasing gradient)
