This document provides background information and learning activities about describing motion for a 7th grade science class. It defines key terms like distance, displacement, velocity, speed, and acceleration. It also provides illustrations to distinguish between distance and displacement. The learning activities include true/false questions to test understanding of distance vs displacement, calculation exercises involving distances and displacements using diagrams, speed problems requiring calculating speed from given distances and times, and open-ended questions about identifying speed and the factors and materials needed. The document aims to help students describe the motion of objects using these quantitative measures.

LEARNING ACTIVITY SHEET
Describing Motion of an Object
Background Information for Learners
Motion is a continuous change in the position of an object with respect to a stationary object. It is
described in terms of displacement, distance, velocity, acceleration, time and speed. Motion: A body is said to
be in motion when it changes its position with reference to a fixed reference point called the origin.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its
motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's
overall change in position.
Fig. 1. Illustration of the difference between distance and displacement.
After learning the difference between distance and displacement, it is also important to know the rate
of an object that is in motion. It is best described when we include the element of time.
In physics, Motion is the change with time of the position of an object. In both cases all points in the body
have the same velocity (speed – distance per unit time of an object in a given direction) and the same
acceleration (time rate of change of velocity).
Learning Competency with Code
Describe the motion of an object in terms of distance or displacement, speed or velocity, and acceleration.

ACTIVITY 1
TRUE OR FALSE
Directions: Write TRUE if the statement describes distance or displacement, and write FALSE, if the statement
does not describe Distance or displacement. Write your answer on the space provided.
______1. The total length travelled by a moving object is called Distance.
______2. Displacement has both magnitude and direction.
______3. Distance is a scalar quantity.
______4. Distance has direction.
______5. Displacement is equal to the distance travelled by an object.
______6. Displacement is the measure of how far an object.
______7. Distance refers to the shortest path travelled between the origin and final position.
______8. Distance and displacement are the same when an object travels in straight direction.
______9. A car covered 100 m from house to the market is an example of distance.
______10. Displacement is zero when the starting and ending up of an object is at the same location
