Y7 Forces Test

What is a force?

• a push or a pull

• change in speed

• change in direction

Choose the option that is a contact force.

• Gravity

• Friction

• Speed

The diagram shows the forces acting on a boat. The boat is moving towards the right.

Choose the pair of forces that are balanced.

• A and B

• A and C

• B and D

Which piece of equipment is used to measure force ?

• Ruler

• Newton meter

• Balance

• Stop clock

Choose which force is represented by arrow D.

• Water resistance

• Gravity

• Upthrust

A student measured force using a broken piece of equipment and repeated it three times. The three measurements were 5.7 N, 5.7 N, and 5.8 N. The student's measurements are (a)  

• accurate.
• precise.
• an average.

A student sets up an experiment to investigate how force affects the extension of a spring, as shown in the diagram

Choose the letters where extension of the spring is measured.

• A to B

• B to D

• B to C

The student carried out this experiment to investigate the effect of different amounts of force on the extension of a spring and recorded these results:

Choose the error the student has made.

• The intervals on the y-axis are too large so not all the data would fit in

• The intervals on the x-axis are too large as it goes up higher than it needs to

• The axes go up in regular intervals rather than irregular intervals

Choose the correct independent variable in this extension of a spring investigation.

• Size of force

• Length of spring

• Type of spring

Choose the size of the resultant force acting on this car.

• 700 N

• 1700 N

• 2700 N
