Factors That Affect Frictional Force

What are the factors that affect
a frictional force?

A frictional force is influenced by factors such
as the type of surface and mass of the object.

Experiment 1 Type of Surface

Problem statement How do the type
of surfaces affect
frictional force?

If the mass of the
trolleys is the same,
which trolley is easier
A B
to push?
cement floor grass
Aim To investigate how types of surfaces affect frictional force.

Apparatus and materials needed
are toy car, rubber band, plastic
sheet, a piece of cardboard, Let us investigate using a toy
a piece of carpet, and measuring car moving on different types
tape. of surfaces.

Construct your hypothesis based on the problem
statement. Identify the manipulated variable,
responding variable, and constant variables in this
experiment.

In this investigation:
1. Plan the steps to carry out this experiment using the given
apparatus and materials.
2. Conduct the experiment.
3. Record the results in a suitable table.
4. Make conclusions based on the experiment.
5. Write a report of the experiment.

The operational definition for frictional force in this experiment
102 6.2.2 is the measurement of the distance travelled by the toy car on
different types of surfaces.
