What is the apparatus for the average speed down a slope of increasing height?
Metre rule, stopwatch, track or runway, ball bearing or trolley, wooden blocks.
What is the method for the average speed down a slope of increasing height?
- Measure height of ramp using a ruler.
- Measure distance of ramp using a ruler.
- Measure time for the ball bearing /trolley to travel the distance using a stopwatch.
- Change the height of the runway, repeat the experiment and average.
- Repeat at 6 different heights.
What does the speed v.s. height graph show?
It is a curved diagonal line that curves off. This means that the average speed starts to level off after when the height of the ramp gets increased.
What is the apparatus for Hooke’s law practical?
Spring, 100g masses on hanger, retort stand and clamp, ruler, g-clamp.
What is the method for Hooke’s law practical?
- Measure natural length of spring N using ruler.
- Add 100 g mass to spring.
- Measure total length of spring L when loaded using ruler.
- Repeat for masses 100- 700g.
What is the Hooke’s law graph?
It is a force Vs extension graph.
The graph is a straight diagonal line through the origin but curves when the limit of proportionality is exceeded.
What is Hooke’s law?
The extension of a spring is directly proportional to the force applied provided the limit of proportionality is not exceeded.
