If a satellite in orbit round the Earth were made to stop and then released, it would...

• fall inwards

• orbit backwards

• float outwards

• stay where it was

At the centre of our solar system is...

• Jupiter

• the Moon

• the Earth

• the Sun

A block with a base area of 4 cm² exerts a force of 10 N on a table. The pressure exerted is

• 0.25 N/cm²

• 2.5 N/cm²

• 10 N/cm²

• 40 N/cm²

A spring extends by 9 cm when a force of 12 N stretches it. A 4N force will extend it by

• 1 cm

• 3 cm

• 27 cm

• 48 cm

A cup has a mass of 250 g. If gravity exerts a force of 10 N on each kg, its weight is

• 2.5 kg

• 2.5 N

• 25 N

• 250 g

The nearest planet to the Sun in our solar system is

• Earth

• Mars

• Mercury

• Venus

The one on this list that is a force is...

• density

• mass

• pressure

• weight

A unit of pressure is...

• g/cm³

• N

• N/cm²

• N.cm

A 10 cm spring has 1 N hung from it. Its length increases by 2 cm. With 3 N the length will be

• 6 cm

• 16 cm

• 22 cm

• 36 cm

We know that Mars is a planet because it...

• appears bright in the night sky

• orbits the Earth

• orbits the Sun

• spins on its axis
