Making generalizations and abstractions about the lesson
How will you describe the motion of an object?
Background Information of the Teacher
* When you apply force on any object, the object will move and change its position.
* Motion is a change in position measured by distance and time. Motion depends on the distance travelled and the length of time.
* When an object changes position over time when compared with a reference point we say that the object is in motion.
* All movement are compared with a background that is assumed stationary. This background is called a point or frame of reference.
Evaluation
Direction: Put check (/) if the objects are in motion and cross(x) if not.

Making generalizations and abstractions about the lesson
How is the speed of objects in motion measured?
What units are used to express the speed of an object?
Background Information for the Teachers
The speed of any object in motion is the rate at which the object moves.
Speed depends on distance travelled and the length of time travelled. A meter or kilometer is used to measure the distance. Meter is used for measuring short distances while kilometer is used for measuring long distances. Time is measured in seconds or hours.
Seconds is used for short length while hour is for long length of time in long distances. To find the speed, you will divide the distance travelled by the length of time. Speed is expressed in meter per second (m/s) or kilometer per hour (k/h). You can simply compute for the speed if you know the distance and the time travelled. Velocity is the speed of the object in a particular direction
