Year 9 CS Physic Revision

What is the instrument use to measure volume?

• measuring tape

• ruler

• measuring cylinder

• stopwatch

Which of the following is NOT the correct technique for using measuring cylinder?

• Place the measuring cylinder on a flat surface.

• When reading the scale, the meniscus and your eye must be in the same level.

• Hold the measuring cylinder with your hand when reading the scale.

What is defined as the distance travel per unit time?

• speed

• acceleration

• force

The diagram show speed-time graph of a car. At what time does the car moves at constant speed?

• between 10 and 20 second

• between 0 and 10 second

• between 20 and 30 second

The diagram show speed-time graph of a car. At what time is the car at rest?

• at 10 second

• at 20 second

• at 30 second

The diagram show speed-time graph of a car. How can we find distance travel by the car?

• find area under the graph

• use formula distance = speed x time

• use formula force = mass x acceleration

What is the name of this instrument?

• force-meter

• electronic balance

• beam balance

What is the correct formula to calculate density?

• density = mass / volume

• density = mass x volume

• density = mass + volume

How do we find the volume of an irregular object?

• Use measuring cylinder

• Use formula to calculate

• By finding out the density first

What is the formula use to calculate spring constant k?

• k = F / e

• k = F x e

• k = e / F
