Hooke's law
I can describe and explain the relationship between the extension of a spring and the force stretching it.
Hooke's law
I can describe and explain the relationship between the extension of a spring and the force stretching it.
Lesson details
Key learning points
- A line of best fit can show the relationship between variables clearly.
- The extension of a spring increases the same amount for each equal sized increase in force.
- The extension of a spring is directly proportional to the force applied.
- A spring is elastic because it returns to its original length when a force is removed.
- Hooke's law describes the behaviour of springs.
Common misconception
The line of a graph must go through all of the points.
Get pupils to invent plots to add to a graph showing a line of best fit that include small mistakes in the measurements.
Keywords
Line of best fit - A line of best fit passes between a set of data points on a graph to show the pattern.
Directly proportional - Variables are directly proportional when one is a constant multiple of the other.
Elastic - A spring is elastic when it returns to its original length after forces are removed from it.
Hooke's law - Hooke's law describes the behaviour of a spring when it is stretched.
