P6 Science Revision 10 (Physical Science)

The diagram shows a measuring tape used by tailors.

Why is the measuring tape suitable for measuring curved lengths along human bodies?

• It is strong.

• It is flexible.

• It is waterproof.

• It is an electrical insulator.

Study the circuit.

One bulb is blown and three bulbs remain lit. Which bulb is blown?

• A

• B

• C

• D

Which of the following is not an example of the effects of a force?

• A piece of paper is folded into an aeroplane.

• The seeds from a plant are dispersed by wind.

• The temperature of a pot increases when it is heated.

• The speed of a ball increases when it rolls down a slope.

The diagram shows the moment when a rubber ball hit the ground. After the bounce, the ball reached a lower height than where it started.

What was the energy conversion at the moment when the ball hit the ground?

• potential → kinetic

• kinetic → potential

• kinetic → potential + sound

• kinetic + sound → potential

In a wooden box, objects P and Q are placed touching each other. Heat flows from P to Q.

Which statement explains why heat flows from P to Q?

• P has more mass than Q.

• P is at a higher position than Q.

• P is at a higher temperature than Q.

• P is a better conductor of heat than Q.

Ben could easily push a sofa when no one sat on it.

However, he found it much harder to push the sofa when Cindy sat on it.

Which of the following is the best explanation?

• There was a greater frictional force between the sofa and the floor.

• There was a greater frictional force between the sofa and Ben's hands.

• There was a greater gravitational force between the sofa and the Earth.

• More kinetic energy had to be converted into gravitational potential energy.

Study the set-up. The volume of the container is 50 cm³.

Using the pump, 5 cm³ of water and 10 cm³ of air are added into the container. What is the final amount of air in the container?

• 20 cm³

• 30 cm³

• 35 cm³

• 45 cm³

Which of the following is correct about the brightness of the bulbs?

• 1

• 2

• 3

• 4

The volume of an object can be measured using a measuring cylinder. The object is first placed into the water. Then the change in the water level is observed.

The table shows the properties of four objects, A, B, C and D.

For which object can we measure its volume using the above method?

• A

• B

• C

• D

Four similar pots of plants, A, B, C and D, are placed at different places as shown.

For these plants to grow well, the soil must be kept wet. Which pot should be watered most often?

• A

• B

• C

• D
