Pushes and Pulls
You push doors. You pull open drawers. You kick (push) a ball. You open a bag (pull). Every movement in the world happens because of a PUSH or a PULL. These are called FORCES. Understanding forces is the FIRST LESSON in physics.
What Is a Force?
A FORCE is any push or pull on an object. Forces can:\n\n- Start something moving\n- Stop something moving\n- Speed something up\n- Slow it down\n- Change direction\n- Change shape\n\nWithout a force, things stay still. With a force, things move or change.
Pushes
A PUSH moves something AWAY from you.\n\n- Pushing a shopping cart\n- Kicking a ball\n- Pushing a door open\n- Typing on a keyboard\n- Pressing a button\n- Jumping (your legs push the ground — ground pushes back!)\n\nPushes move things forward or away.
Pulls
A PULL moves something TOWARD you.\n\n- Pulling a wagon\n- Tugging a rope\n- Opening a drawer\n- Picking up a toy\n- Flushing a toilet (chain pulls!)\n- Gravity (pulls everything TOWARD Earth)\n\nPulls bring things closer.
What is a FORCE?
Bigger Force = Bigger Effect
The STRONGER the push or pull, the MORE the object moves.\n\n- Tap a ball lightly → rolls a little\n- Kick it hard → flies across the yard!\n\nSame with pulls. A gentle tug barely moves something. A strong yank moves it a lot.\n\nStrong force = big change. Small force = small change.
Invisible Forces
Some forces you CANNOT see but they still work:\n\n- **GRAVITY** — pulls everything toward Earth. That's why things fall.\n- **MAGNETISM** — pulls some metals toward magnets.\n- **FRICTION** — pushes BACK when things slide (stops them).\n- **WIND** — pushes leaves, flags, balloons.\n\nYou can't see these forces, but you can FEEL their effects.

Push-Pull Scavenger Hunt
In your home, find:\n\n1. 5 things that need a PUSH (doors, buttons, pedals)\n2. 5 things that need a PULL (drawers, handles, zippers)\n3. Now try the OPPOSITE — push what normally pulls. Can the drawer open with a push? (No — it just pushes in!)\n4. Some things need both (like opening a car door).
Tug of War
1. Grab a rope or scarf with a friend.\n2. Both pull HARD.\n3. If one pulls harder, they win!\n4. Now try one strong person vs two smaller ones.\n5. Who wins? The side with MORE force.\n6. That's how forces work — bigger wins.
