year 9 physicS

9K SPEEDING UP

In this topic you will learn about how to measure and calculate speed and acceleration. You will draw graphs to show speed and learn about how engineers design things to go fast!

Here are the learning objectives for this topic:

I can

  • Put objects in order by their speed
  • Name some units that speed is measured in
  • Describe how speed can be measured
  • Calculate the average speed of an object
  • Draw a distance time graph

I understand
  • That speed is calculated using the distance and time
  • Why objects speed up or slow down
  • How humans design objects to go faster
  • What streamlining is
  • That forces influence the speed of an object
  • How and why speed changes over time on a falling object
  • The forces which act on a falling object
  • What a speed time graph shows

Look at the Bitesize revision section on speed, distance and time.

You can have a look forward to IGCSE level in Unit P1.

Try these motion graph practise questions from physics classroom. Answer on paper and then check on the website.

Here is a harder quiz from McGraw-Hill

TRY THE MOVING MAN SIMULATION

Choose his speed and acceleration and watch how he moves! This program also draws motion graphs.
