5.1.2 Kinematics part 1 `Graphs'
You should be able to:
(a) define displacement, speed, velocity and acceleration.
(b) use graphical methods to represent distance travelled,
displacement, speed, velocity and acceleration.
(c) find the distance travelled by calculating the area under a
(d) use the slope of a displacement-time graph to find
velocity, and of a distance-time graph to find speed.
(e) use the slope of a velocity-time graph to find acceleration.
(h) interpret displacement-time and speed-time graphs for
motion with non-uniform acceleration.…read more
Definitions for linear motion (i.e. in a straight line)
distance is how far you travel between any two points by
any route. It is a scalar quantity.
displacement is the minimum "as the crow flies" distance
between two points. It is a vector quantity, so it has
speed is how fast you go, the rate of change of distance.
velocity is rate of change of displacement. It must have
Acceleration can be used as both a vector and a scalar
quantity. It is the rate of change of speed or velocity.…read more
