MACRO STATEMENT
DEMONSTRATE THE RELATIONSHIP BETWEEN
FORCE AND MOTION. |
II. KNOWLEDGE STATEMENTS
A STUDENT SHOULD KNOW THAT:
A. THE MOTION OF AN OBJECT CAN VARY
IN SPEED AND DIRECTION.
- An object can be described by the
place in space that it occupies. For example,
- Orientation: upside down, right
side up, backward, forward
- Position in relation to another
object: in front of, behind, above, below, inside, outside
- Speed: fast or slow
- Motion of an object can be affected
by the surface of the object and the surface of the material
the object touches (friction).
B. THE POSITION AND MOTION OF AN OBJECT
CAN BE CHANGED BY PUSHING AND PULLING.
- Position of an object can be changed
by an event in which the object is involved.
- An object can be pushed or pulled
to cause the object to change its motion.
- The change in the motion of an
object is in the direction of the push or pull exerted
on the object.
C. THE CHANGE IN THE POSITION AND MOTION
OF AN OBJECT IS RELATED TO THE STRENGTH
OF THE FORCE.
- The push or pull (force) needed to
cause a change in motion of an object depends upon the weight
of the object. The heavier the object, the greater the push
or pull needed to produce the same change in motion.
- The rougher the surface, the greater
the push or pull needed to move an object on that surface.
D. SOME FORCES ARE INVISIBLE AND CAN
ACT AT A DISTANCE.
- The earth's gravity pulls any object
toward it without touching it.
- A magnetic force can push or pull
certain objects without touching them.
- An electrical force (such as static
electricity) can push or pull certain objects without touching
them.

SKILL STATEMENTS
A STUDENT SHOULD BE ABLE TO:
- Infer from observations and collected
data, that some forces are invisible and can act at a distance.
- Identify and use a reference point
to note the changes in the position and the motion of an object.
- Generalize, from observations, and
recorded and analyzed data, that the motion of an object can
vary in speed and direction.
- Recognize, using observations and
collected data, the cause and effect relationship that a push
or a pull will have on an object.
