PLEASE HELP ME Design a simple experiment that you could carry out in your home to
i) determine the coefficient of static friction between an object and a surface.
ii) prove that the coefficient of static friction is dependent only on the surfaces in
contact, and is not affected by any change in the mass of your object.
(Hint: You might want to look back at the last couple of Support Questions in this lesson,
to help you.)
a) Describe your plan. It must include a list of materials, a diagram of the set-up, and an
explanation of the steps you would take and the data you would collect. (5 marks)
b) Explain how you would analyze the collected data to determine the coefficient of
static friction and prove that it is unaffected by any change in the mass of your object.
(2 marks)
c) State one possible source of error that you might encounter in this experiment and
state the steps you took to minimize or eliminate this source of error. (1 mark)

so easy. just google the electromagnetic waves and it’ll pop up.
