What was the distance fallen by the modelling clay?

• from A to C

• from A to D

• from B to C

• from B to D

What measuring instrument should be used to measure the distance fallen?

The student dropped four pieces of modelling clay, each with a different shape.

For each piece the student measured the time taken to fall the same distance through

the oil.

The student removed each piece of modelling clay from the oil before dropping the

next piece.

Suggest one reason why.

Each piece of modelling clay had the same mass.

Which shape in Table 1 had the smallest resistive force acting against it as it fell?

• cone

• cube

• cylinder

• sphere

Give one reason for your answer to previous question.

How would the time taken to fall change if the modelling clay was dropped through air instead of through oil?

• Time through air would be less.

• Time through air would be more.

• Time through air would be the same

The mass of a piece of modelling clay was 0.050 kg.

gravitational field strength = 9.8 N/kg

Calculate the weight of the piece of modelling clay.

Use the equation:

weight = mass × gravitational field strength

Weight causes the modelling clay to fall through the oil.

Weight is a non-contact force.

Which of the following are also non-contact forces?

• Air resistance

• Magnetic force

• Friction

• Electrostatic force

• tension

Our solar system includes the Sun, planets and moons.

Complete the sentence.

Our solar system is part of the​ (a)   galaxy.

• milky way
• pinwheel
• whirlpool
• andromeda
