Motion

​Observe Figure 1 and Figure 2. Infer in which figure the car has moved.

Multiple Choice

1.   Is there a change in the position of the car in Figure 2?

• There is a change in the position of the car in Figure 2.

• Nothing change in the position of the car in Figure 2.

Multiple Choice

2.   What does the change in position of the car in Figure 2 mean?

• The change in position of the car in Figure 2 means that the car has moved. There is motion.

• No change in position of the car in Figure 2. There is no motion.

Multiple Choice

3.   How do we know the car has moved?

• The car hasn't moved because there's no changes in their position.

• We know the car has moved because it changes position.

Multiple Choice

4.   What is your basis in describing the car’s motion?

• There's no basis in describing the car’s position

• The basis in describing the car’s position is the reference point or frame of reference.

Take note of this!

​You know that something has moved because you can see that it has changed position. Position is the location of an object. It is an object’s distance and direction from a reference point. A reference point, also called frame of reference, is the starting point you choose to describe where the object is. The car in the first activity has changed position when it was a meter away from the trees. This process of changing an object’s position is called motion.

In this example, buildings and trees are the frame of reference. From figure 1 to figure 2, the car changed its position. Therefore, there is motion.​

Factors Affecting Motion

​

Q3 W1 Lesson 3​

By John Daniel P. Gumban

​Take note of this!

Many things around us can move. Movement is also called motion. Motion is movement from one position to another. Motion can be fast or slow. This property is called speed. Motion can be back and forth, up or down, round in a circles, straight in zigzag. We can change the speed in our motion too. We can go faster or slower. Everything needs a push or a pull to get in moving. This push and pull is called force. A force can also slow something down, or get it to change position. Friction can also slow something down. Friction is the force that occurs in rubbing two objects against each other and it slows down the moving object.

​Take note of this!

Gravity is a force which pulls objects towards the center of the earth. Every object has gravity force. The amount of pulling force depends on the mass of the object and their distance from each other. Objects with a larger mass have a larger force. Objects with a small mass have a smaller force.

Speed

​

Q3 W1 Lesson 3​

By John Daniel P. Gumban

​Take note of this!

When something is moving, you often ask how fast it is going, or what its speed is. Speed is a concept in motion which is the rate at which an object covers distance. You can find the speed of an object if you know the distance travelled by the object and the time taken by the object to travel this distance. You can use the formula to find the speed of an object.

​

Speed = Distance ÷ Time

​Take note of this!

-Motion is the change in an object’s position.

-Position is the place where you are.

-An object’s position is described by its distance and direction from a reference point.

-Reference point, also called frame of reference, is the starting point you choose to describe where an object is.

-The types of motion are rectilinear motion, circular motion, periodic motion and rolling motion.

-Force is applied to make anything move.

-Force is a push or a pull.

​Take note of this!

-Friction is the force that occurs in rubbing two objects against each other and it slows down the moving object.

-Gravity is a force, which pull objects towards the center of the Earth.
