- Distance-Time Graphs
- Gradient of
line =
SPEED
- For an object at a
constant speed:
SPEED=DISTANCE
TRAVELLED/TIME
TAKEN.
- Unit of speed is metre/second
- Reading the graph
- stationary=horizontal line
- accelerating/decelerating=curve
- constant
speed=diagonal
line
- Velocity and acceleration
- velocity=speed in a given direction
- acceleration=change of velocity per second.
- unit is the m/s2
- acceleration=change in velocity/time taken
- velocity/time graphs
- horizontal line=constant speed
- gradient=acceleration
- area under
line=distance
travelled
