How to work with Speed and Velocity

What do you know about speed? Have a look at some of these….

• Elephants can run up to 40 km/h (25 mph)
• A hippopotamus can run faster than a man, and ostriches can outrun horses
• A dolphin can swim at up to 60 km/h (37 mph), whereas a shark can travel at up to 70 km/h (44 mph)
• Fleas can accelerate 50 times faster than a space shuttle, and a honeybee can reach 32 km/h (20 mph)
• Bulls can run faster uphill than down!!

If you are studying GCSE Science, you need to know the difference between speed and velocity, and how to calculate them. Try our new “How to work with Speed and Velocity” guide. Included is an explanation of how to interpret distance/time graphs, and velocity/time graphs. There are examples of how to use the gradient to calculate speed or acceleration, and using the area under a graph to calculate distance travelled. Questions for you to try, and answers to check your understanding can also be found in the guide.
