Calculating speed

Science

In the Measuring and calculating motion unit, they will build on this knowledge to learn how to measure and calculate velocity and acceleration, and how to interpret velocity-time graphs. 

In the Forces unit, pupils learn to accurately describe and explain the actions of forces in a range of situations. 

This unit explores speed, forces, and motion, including effects on objects. It covers deriving equations, calculations, and distance-time graphs. Learn to use force arrows, identify balanced and unbalanced forces, and understand their impact on movement.

Moving by force

The green car started moving before the red car did.

The red car stopped moving before the green car did.

The average speed of the red car is greater than the average speed of the green.

The average speed of the green car is greater than the average speed of the red.

The average speed of the two cars is the same.

Two cars travel along a track for the same amount of time. The green car travels twice as far as the red car. Which of these statements is true?

Which of these equations involving speed, distance and time is correct?

A cyclist travels at an average speed of 15 m/s for 45 seconds. Calculate the distance they travel.

A speedboat travels 70 miles in 3.5 hours. Calculate the speed of the boat.

The table shows the speeds of athletes in races of different lengths. Starting with the longest time, put the athletes into order of how long it took them to finish their race.

The time the motorcycle was travelling for.

Which two pieces of information could you use to work out the speed of a motorcycle after it has finished a journey?

Match the description of movement to the distance travelled in a certain time.

The cars are travelling at the same speed.

After 1 s the red car has travelled further than the blue car.

After 1 s the blue car has travelled further than the red car.

A red car and a blue car start at the same time and travel the same distance along a track. The red car takes 20 s to reach the end and the blue car takes 25 s. Which of the statements are correct?
