MOTION
SCIENCE WEEK IJO QUARTER
Motion is described as a continuous change in position
of a body relative to a reference point, as measured by
a particular observer in a particular frame of reference.
How will you describe your current position? Are you
sitting right now as you read this module? Are you
sitting on a chair in your room beside your bed? Or are
you sitting in the living room in front of the television?
Position and motion can be best described by using a
reference point. Look around you. What things are
moving? How can you say that such things are
moving?
One way or knowing whether an object is moving or
not, is by comparing it with another object that stays
in place or not moving. This will be your reference
point. An object is said to be moving when it is
traveling towards or away from a reference.
Analyze Figure 1. Which object do you think is in
motion? Is it the basketball ring or the ball? Which will
serve as the reference point?
In this image, we can infer that that ball is in motion
with respect to the basketball ring. The ball is falling
while the basketball ring stays still.
Activity 1: "Notion on Motion"
Look around you. Observe objects or bodies that are in
motion. Identify other prominent objects or parts of the
house that will serve as your reference point. List them
down on the table below. The first one serves as your
example. (10 points)
