What is Force? The Power of Pushes and Pulls

Learning Objectives

At the end of this lesson, you are expected to:

• Define force in your own words as a push or a pull.

• Identify actions around you as examples of a push or a pull.

• Classify different everyday actions correctly as either pushing or pulling.

Warm-Up Activity

Take a moment to think about:

• How do you open the door to your classroom?

• How do you move your chair closer to your desk?

• What do you do to get a drink from a water bottle with a flip cap?

Just think about the actions you do. What are your hands doing in each situation?

Lesson Proper

Imagine you are playing a game of piko (hopscotch). You have a small flat stone, your pamato. To start the game, you need to get your pamato into the first square. What do you do? You use your finger to flick it forward. Or, think about when you help at home by getting pan de sal for breakfast. The bread is in a plastic bag. To open it, you use both hands to pull the sides apart.

In both stories, you did something to make an object move or to open something. You applied a force! Force is not a mysterious power. It is something you do every single day.

Main Explanation

What is Force? Force is simply a push or a pull. It is an action that can make things move, stop, or change. You cannot see force itself, but you can always see what force does.

How does it work? A force happens when one object interacts with another. This usually needs contact.

• Push: A push is a force that moves an object away from you.

  • Example: Pushing a swing to make it go.

• Pull: A pull is a force that moves an object toward you.

  • Example: Pulling a wagon.

Important parts you need to remember:

• Force is a push OR a pull.

• Force is an action.

• We see the effects of force, not the force itself.

Real-World Examples

Example at home:

• Push: Pushing the buttons on the TV remote.

• Pull: Pulling a blanket over you when you sleep.

Example in school:

• Push: Pushing your pencil across the paper to write.

• Pull: Pulling out a book from your school bag.

Example in the community:

• Push: A manong driver pushing his kariton (cart).

• Pull: A person pulling the rope of a church bell.

Understanding the Lesson Better

Key Ideas in Simple Words

• In simple words, force is just pushing or pulling.

• Remember that you use force all the time, like when you play, eat, or study.

• A push sends something away. A pull brings something closer.

Step-by-Step Examples

Example 1: Classifying an Action Action: Closing a door.

• Ask: What am I doing to the door? I am moving it.

• Ask: Is the door moving towards me or away from me? It is moving away from me to shut.

• Conclusion: This action is a PUSH.

Example 2: Classifying an Action Action: Tugging on a friend's arm during agawan base (a Filipino game).

• Ask: What am I doing to my friend? I am trying to move them.

• Ask: Are they moving towards me or away from me? I am trying to bring them towards my base.

• Conclusion: This action is a PULL.

Common Mistakes & Clarifications

Common Mistake 1: Many students think that force has to be strong, like a superhero's power.

• Correct Thinking: Actually, even a very gentle action is a force. Gently pushing a paper clip or softly pulling a thread are both examples of force.

Common Mistake 2: Some students mix up push and pull when the action is sideways or up and down.

• Correct Thinking: A simple way to remember is: Ask yourself, "Is it mostly going away from the person doing it?" (Push) or "Is it mostly coming towards the person doing it?" (Pull). For example, lifting a bag up is a pull because you are bringing it towards you (upwards).

Helpful Tips

• Remember the word PUSH-PULL. It reminds you that force is one or the other.

• Imagine the letters: PUSH has an "sh" sound that sounds like something moving away ("shoo!"). PULL has a "ll" that looks like two hands bringing a rope towards you.

For Curious Minds

Did you know that even the Earth is pulling on you right now? This force is called gravity. It is a pull that keeps you on the ground and makes things fall. When you drop your pencil, it's gravity pulling it down to your desk!

Real-World Connection

How can this lesson help you in real life?

• At Home: Understanding pushes and pulls helps you know how to use things safely and properly, like knowing you must pull the plug from the socket, not yank the cord.

• At School: It helps you describe games and sports clearly. You can explain that in sipa, you use your foot to push the rattan ball upward.

• Everywhere: It makes you a better observer of the world. You will start to see the science of pushes and pulls in everything, from a jeepney starting to move to a vendor pulling their cart.

What You Have Learned

• Force is defined as a push or a pull.

• A push moves an object away from you.

• A pull moves an object toward you.

• Everyday actions like opening, closing, throwing, and lifting involve force.

What You Can Do

What You Can Do with This Lesson in Real Life: Here are some ways you could use this lesson:

• You can now look at any action and ask, "Is that a push or a pull?"

• You can understand better how to use tools. For example, you use a pull to open a drawer and a push to close it.

• This will help you when you need to explain how to do something. Instead of just saying "move it," you can say "give it a gentle push to the right" or "pull it towards you slowly."

Your Activity: Force Scavenger Hunt Now, let's be a force detective! Look around your classroom or your home.

1. Find and list ten (10) different actions you see people doing or that you can do yourself. (Example: Writing on the board, Opening a window)

2. Next to each action, write if it is mainly a PUSH or a PULL. You can use the back of your paper or a notebook for your list. Happy hunting
