These diagnostic questions and response activities (contained in the zip file) support students in being able to:
- Calculate the size and direction of the resultant force of two forces acting along the same straight line
- Describe how quickly the speed of an object can be changed if acted on by resultant forces of different size
- Describe how the speed of an object changes throughout the time that a resultant force is acting on it
- Explain how friction and other resistive forces can act to continually reduce the speed an un-propelled object
- Explain why friction and other resistive forces make it necessary to exert a constant force to keep an object moving at a steady speed
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
