If an object moves along a straight line, its motion can be represented by a velocity-time (or speed-time) graph. The gradient of the line is equal to the acceleration of the object.
How do you describe the motion?
You can describe the motion of an object by
its position, speed, direction, and acceleration
. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
How do you describe motion on a position time graph?
Motion can be represented by a position-time graph, which
plots position relative to the starting point on the y-axis and time on the x-axis
. The slope of a position-time graph represents velocity. The steeper the slope is, the faster the motion is changing.
How do you describe the motion of an object on a velocity-time graph?
Note that a motion described as
a changing, positive velocity results in a sloped line
when plotted as a velocity-time graph. The slope of the line is positive, corresponding to the positive acceleration. Furthermore, only positive velocity values are plotted, corresponding to a motion with positive velocity.
How do you describe a distance time graph?
A distance-time graph
shows how far an object has travelled in a given time
. It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. Time is plotted on the X-axis.
What does uniform motion look like on a position versus time graph?
You can determine if an object exhibits uniform motion by looking at a position-time graph of the motion.
If the graph forms a straight line with a constant slope, then the motion is uniform
, and the slope of the graph is equal to the velocity of the object.
When the line of the graph is steeper it means that the motion is slower?
When the slope of the line is steep, the speed is faster than if the slope were flatter. When the
slope of the line is flatter
, the speed is slower. When the slope of the line is horizontal to the x-axis, the speed is zero (the object is not moving).
How do you read a motion graph?
V-T graph displays
the variation of an object’s velocity as a function of time
. The slope of the v-t graph is acceleration a. Acceleration is the rate of change of velocity.
What type of graph is used to represent motion of an object?
The motion of objects can be presented in pictorial form by their
distance-time graphs
. The distance-time graph for the motion of an object moving with a constant speed in a straight line.
What are the different types of graphs of motion?
Ans: There are two main types of graphs in motion, namely
displacement-time graph and velocity-time graph
.
What is the advantage of a distance-time graph?
1. Distance-time graphs
provide a variety of information about the motion when compared to the data presented by a table
. 2. From the distance-time graph, we can find the distance moved by a body at any instant of time.
What are the uses of a distance-time graph?
(i)
It tells us about the position of the body at any instance of time
. (ii) From the graph, we can see the distance covered by the body during a particular interval of time. (iii) It also gives us information about the velocity of the body at any instance of time.
How do you simplify graphs?
- 1) Remove Backgrounds.
- 2) Remove Duplicate Labels.
- 3) Remove Borders in Chart Elements and Background.
- 4) Reduce Colors.
- 5) Remove Special Effects Like Shading and Shadows.
- 6) Get Rid of Bold Text.
- 7) Lighten Secondary Data Labels.
- 8) Lighten or Remove Lines.
What are some examples of uniform motion?
- The hr. …
- An airplane cruising at a level height and a steady speed.
- A car going along a straight level road at steady speed.
- A vibrating spring in a sewing machine.
- A ship steaming on a straight course at steady speed.
- A train going along the tracks at steady speed.
What does the slope of a distance time graph indicate?
In a distance-time graph, the slope or gradient of the
line is equal to the speed of the object
. The steeper the line (and the greater the gradient) the faster the object is moving.
What can you say about the motion of an object?
You can describe the motion of an object by
its position, speed, direction, and acceleration
. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
