Study Notes
Mass and Weight
- Mass is the amount of matter in an object.
- Mass does not change when the location changes.
- Weight is the force of gravity pulling on an object.
- Weight changes depending on the location.
- Weight = Mass x Gravitational field strength
Stretching
- An elastically behaving object returns to its original shape when the force is removed.
- A plastically behaving object deforms and stays in its new shape after the force is removed.
- The elastic limit is the point of permanent deformation.
Hooke's Law
- Hooke's Law states that the extension of a spring is directly proportional to the force applied (up to the elastic limit).
- This means that if you apply three times the force, the spring will stretch three times further (while within its elastic limit).
- The relationship between force and extension is linear; force is directly proportional to the extension.
- Hooke's Law equation: Force = Spring Constant x Extension
Combining Springs (Series and Parallel)
- Springs in Series: When springs are connected end-to-end. The total extension is equal to the extension of one spring multiplied by the number of springs.
- Springs in Parallel: When springs are connected side-by-side. The total extension is equal to the extension of one spring divided by the number of springs.
Graphs
- Graphs should have labeled axes with equal scales.
- The line of best fit should be a straight line.
- The gradient of the graph is the spring constant.
