An explanation and practice in reading forcemeters in newtons

Forcemeters

(2 pages)

To know that ‘Newton’ is the unit of force

To  use a force meter carefully to measure forces

Record the measurements of the forcemeters. Measure own objects and record in newtons (N)

Sliding

(1 page)

To know that ‘Newton’ is the unit of force

Explanation on experiment using a forcemeter. Fill in gaps. Do own similar experiment

Friction

(1 page)

To know that there is a force between an object and a surface which may prevent the object moving

An explanation about friction and some questions to answer

Friction questions

 (1 page)

To know that there is a force between an object and a surface which may prevent the object moving

A set of questions to show what has been learnt through the unit

Friction and forcemeters

(1 page)

To make and record careful measurements and present them in a bar chart

Read the forcemeter when you do the given tasks. Make a bar chart after testing surfaces and measuring the newtons

 

Friction and surface textures

 (2 page)

To explain conclusions in terms of the roughness or smoothness of the surfaces

Complete the experiment of friction on different surfaces. Record results and answer the questions about friction

Friction and lubrication

(2 pages)

To explain conclusions in terms of the roughness or smoothness of the surfaces

Complete the experiment of friction on lubricated / non lubricated surfaces. Record results and answer the questions about friction

Jelly and friction

(1 page)

To explain conclusions in terms of the roughness or smoothness of the surfaces

Find out how easy it is to move jelly cubes and explain how friction worked.

High or low friction

 (1 page)

To learn that the force between two moving surfaces in contact is called friction
