Motion at changing speeds
Various ways to describe motion
This task is about describing the motion of a vehicle in different ways.
Here are several ways to describe motion:
|
| time-position graph |
| |
time-velocity graph |
position |
|
|
velocity |
|
|
time |
|
|
time |
|
plot: the position of the vehicle at different times
(click the arrows with the mouse to see the relation between different descriptions)
|
Verbal description:
The vehicle is moving from left to right at increasing speed. It is accelerating.
|
|
The Constant acceleration tool
represents motions for which the time-velocity graph
is linear.
Describe motion in various ways
Below are several time-velocity graphs of
vehicles.
Describe the motion of each vehicle in various ways:
|
Verbal description: write a sentence
describing the motion of each vehicle.
|
|
|
Time-position graph: sketch a graph showing the
dependence of vehicle position on time.
|
|
|
Plot: sketch a plot showing vehicle
position at various times.
