time, speed and distance

During this topic you will learn how to recognise the relationship between speed, distance time.  You will also learn how to calculate speed.

Learning Checklist

I can measure the size of a force and use the right units.
I can compare the speeds of different things.
I can describe what speed means scientifically and use the correct units.
I can use the relationship between speed, distance and time.
I can describe situations where forces are balanced or unbalanced.
I know that if the forces on an object are balanced, then it moves at a constant speed.
I can use the relationship between pressure, force and area in different situations.
I know that if an object’s speed changes, then the forces acting on it must be unbalanced.
I know what acceleration is.
I can draw distance–time graphs and interpret them correctly.
I can use the equation for speed in calculations and I can convert different units.
