We use mass balance to measure mass.

We compare the mass of the object with the masses.

We measure mass in kilograms (kg) and grams (g). The kilogram is a unit used commonly in everyday life.

1 000 g = 1 kg.

To experience or understand what mass fells like, imagine you have an object on a skateboard. Give the object a good push. How fast does it start to move? You are feeling the effect of its mass!

Multiple Choice

Which one will be easier to push?

• the cat
