Displacement, Velocity,Speed, Instantaneous Speed, Speed Acceleration, Gradient.
You should:
(c) apply graphical methods to represent displacement, speed, velocity and acceleration;
(d) determine velocity from the gradient of a displacement against time graph;
(e) determine displacement from the area under a velocity against time graph;
(f) determine acceleration from the gradient of a velocity against time graph.
Watch the video at the top of the page.
The following are examples of graphs where velocity is varying with time.
Remember that velocity is a vector and so if the line is above zero on the yaxis it means there is a positive velocity and if it is below zero it is a negative velocity.
A slope means that the velocity is changing – acceleration. This can be getting quicker or getting slower (deceleration is also called retardation)
A positive flat line shows that there is a constant (uniform) positive velocity.
A rising positive line means that there is a constant positive acceleration.
To find the displacement of an object using a velocitytime (vt) graph we find the area underneath the graph.
To find the acceleration of an object using a vt graph we take the gradient. If we have a sloping line we can find the instantaneous acceleration be taking a tangent at a point.
These ideas will be looked at in more detail in lesson 8.

Have a look at the following site and check your answers. Don't move on until you have correctly answered all the multiple choice questions and understand why they are correct:
If you would rather look at this site in a separate window, then follow the link: velocitytime graphs (http://dev.physicslab.org/Document.aspx?doctype=5&filename=Kinematics_
UniformAccelerationVelocityTimeGraphs1.xml)
Look at the graph and then answer the questions:
1 What does the slope of a velocitytime graph represent?
2 Calculate the gradient and give the units for each section: A; B and C.
3 What is the total displacement?
