Velocity-Time Graphs: interpretation, gradient and displacement

Notes

Learning Objectives: Understanding that the motion of objects can be represented in a velocity-time graph and understanding how these graphs can be interpreted. Success Criteria: At the end of this activity you will be able to: Recall what velocity-time graphs look like for objects that are travelling with a positive acceleration, negative acceleration and constant velocity.• Calculate distance (displacement) and acceleration using velocity-time graphs.• Interpret velocity-time graphs to describe the motion of an object• Construct a velocity-time graph• Vocabulary: Speed or Velocity (m/s)• Acceleration or deceleration (m/s/s or m/s2)• Axes• Gradient• Area under the curve• Graphs can be used to show the motion of objects. These graphs are called motion graphs. Remember the features of graphs? All graphs have an: x-axis (horizontal)• y-axis (vertical)• each axis has a title and a unit.• the title tells you which variable is being plotted along that axis.• the unit tells you the unit that the variable is measured in.• Data is plotted on a graph, data points are joined together with lines. The slope of this line is called the gradient. Gradient = rise ÷ run m = Δy ÷ Δx A steep line has...
