Distance-Time Graphs
- For a altitude-time graph, the distance never decreases.
- When the object is stationary, the altitude-time graph volition be horizontal.
- The gradient of a altitude-time graph is the instantaneous speed of the object.
- For straight line with positive gradient, it means that the object is travelling at uniform speed
- There is no straight line with negative gradient (every bit the altitude never decreases)
- For curves, information technology ways that the object is travelling at not-compatible speed
Displacement-Time Graphs
- The details are like as distance-time graphs, except that the altitude is at present displacement, and speed is at present velocity.
- Ane minor divergence: There is a directly line with negative gradient, it ways that the object is travelling at uniform velocity in the opposite direction.
Velocity-Time Graphs
- When the object is stationary, it is a straight horizontal line at 0.
- When the object is undergoing uniform motion, it is a directly horizontal line at $5 \, \text{1000 s}^{-one}$, where 5 is the velocity of the object.
- For straight line with positive slope, information technology ways that the object is accelerating.
- For straight line with negative gradient, it means that the object is decelerating.
- For curves, it means that the acceleration of the object is changing.
- The area nether the graph is the change in the displacement of the object.
Dispatch-Time Graphs
- Surface area under graph is the change in the velocity of the object
Summary of Kinematics Graphs
The figure beneath shows the displacement-fourth dimension graph, velocity-fourth dimension graph and acceleration-fourth dimension graph for the respective country of motility. It serves equally a summary of the text in a higher place.
The figure below shows the relationship between displacement-time graph, velocity-fourth dimension graph and acceleration-fourth dimension graph.
Self-Exam Questions
Can you tell from a deportation-time graph whether an object is stationary?
Show/Hide Answers
Yes. If the object is stationary, it will appear as a horizontal line on a deportation-time graph.
How tin you obtain the average velocity and instantaneous velocity from a displacement-fourth dimension graph.
Evidence/Hide Answers
The average velocity tin can be found by using $\frac{\text{total displacement}}{\text{total time taken}}$.
The instantaneous velocity at a signal in time can be found from the gradient of the tangent to that point in time.
Can y'all tell from a velocity-time graph whether an object is stationary?
Testify/Hide Answers
Yes. If the object is stationary, the velocity-time graph will be a horizontal line at $\text{v}=0$.
How would y'all obtain the acceleration of an object from a velocity-fourth dimension graph? What does the expanse under a velocity-time graph correspond?
Show/Hibernate Answers
The acceleration of an object at a point in time tin can exist obtained from the gradient of the tangent to that point in fourth dimension.
The expanse under a velocity-time graph represents the full distance traveled.
Can you tell from an acceleration-time graph whether an object is stationary?
Show/Hibernate Answers
No, you cannot. Practice you lot know why?
