💡 What is Force?

A force is a push or a pull.

A force can change, or try to change, an object's state of rest, speed, direction, shape or size.

🌈 Rainbow Mind Map of Force

FORCE

A push or pull acting on an object

🔴 Meaning

Force is an interaction that can affect motion or shape.

🟠 Main Actions

• Push
• Pull

🟡 Effects

• Start or stop motion
• Change speed or direction
• Change shape or size

🟢 Contact Forces

• Muscular force
• Frictional force
• Mechanical force

🔵 Non-contact Forces

• Gravitational
• Magnetic
• Electrostatic

🟣 Measurement

The SI unit of force is the newton (N). A spring balance can measure force.

✨ Five Important Effects of Force

🚀

1. Start Motion

Kicking a stationary football makes it move.

🛑

2. Stop Motion

Applying bicycle brakes can stop a moving bicycle.

⚡

3. Change Speed

Pedalling harder can make a bicycle move faster.

↪️

4. Change Direction

Hitting a moving ball sideways changes its direction.

🧽

5. Change Shape

Squeezing a sponge changes its shape and size.

🧠

Remember

A force may act without producing visible motion, such as pushing a strong wall.

🧲 Types of Force

🤝 Contact Forces

These forces act only when objects touch each other.

Muscular force Frictional force Mechanical force

Examples: pushing a trolley, pulling a rope, writing with a pencil and using brakes.

✨ Non-contact Forces

These forces can act even when objects do not touch.

Gravitational force Magnetic force Electrostatic force

Examples: a falling apple, a magnet attracting iron pins and a rubbed comb attracting paper bits.

Force	Contact needed?	Simple example
Muscular force	Yes	Lifting a school bag
Frictional force	Yes	Brakes slowing a bicycle
Mechanical force	Usually through a machine	A crane lifting a load
Gravitational force	No	A fruit falling to the ground
Magnetic force	No	A magnet attracting a pin
Electrostatic force	No	A rubbed balloon attracting hair

⚖️ Balanced and Unbalanced Forces

Balanced Forces

Equal forces act in opposite directions. The overall force is zero, so there is no change in the object's motion.

Example: A book resting on a table.

Unbalanced Forces

The forces are not equal. The overall force is not zero, so the object's motion can change.

Example: One team pulling harder in tug-of-war.

Quick clue: Equal and opposite forces balance. A stronger force in one direction produces an unbalanced force.

🛞 Friction — Friend and Foe

Friction Helps Us

• Walk without slipping
• Write with a pencil
• Grip objects
• Stop vehicles using brakes

Friction Can Cause Problems

• Produces heat
• Wears out moving parts
• Slows objects down
• Wastes some energy

🎛️ Mini Simulations

Simulation 1: How far will the ball move?

Choose the amount of force. Watch the ball move. This is a simple visual model, not an exact scientific measurement.

Small Push Medium Push Strong Push

⚽

A small push changes the ball's motion, but it travels a shorter distance in this model.

A medium push gives the ball a bigger change in motion.

A stronger push gives the ball the greatest change in motion in this model.

Simulation 2: Friction Race

Give the toy car the same push on three surfaces. Which surface lets it travel farther?

Rough Carpet Smooth Floor Very Slippery Surface

🚗

Rough surfaces usually produce more friction, so the car stops sooner.

A smooth floor has less friction than rough carpet, so the car moves farther.

A very slippery surface provides very little friction, so the car travels farthest in this model.

Simulation 3: Balanced or Unbalanced?

Choose the force situation and observe the box.

Equal Forces Stronger Right Push Stronger Left Push

➜

BOX

⬅

The equal opposite forces balance, so the box does not move to either side.

The force towards the right is stronger, so the forces are unbalanced and the box moves right.

The force towards the left is stronger, so the forces are unbalanced and the box moves left.

🎮 Fun Learning Games

Game 1: Push or Pull?

Tap your answer. Feedback appears immediately.

1. Opening a drawer towards you is a...

Push

Try again. The drawer comes towards you.

Pull

Correct! You pull the drawer towards yourself.

2. Closing a door away from you is usually a...

Push

Correct! You apply force away from yourself.

Pull

Try again. The door is moving away from you.

3. Tugging a rope in tug-of-war is a...

Push

Think about the rope coming towards your team.

Pull

Correct! Each team pulls the rope.

Game 2: Contact or Non-contact?

1. A magnet attracts an iron pin without touching it.

Contact

The magnet can act from a small distance.

Non-contact

Correct! Magnetic force can act without contact.

2. Your hand pushes a chair.

Contact

Correct! Your hand must touch the chair.

Non-contact

Your hand and the chair are touching.

3. Earth pulls a falling leaf downward.

Contact

Earth does not need to touch the leaf directly.

Non-contact

Correct! Gravity is a non-contact force.

Game 3: Tap-to-Flip Force Cards

Tap a card to reveal its answer. Tap again to turn it back.

🍎 Why does an apple fall? Gravitational force
Earth pulls it downward.

🧲 What attracts an iron pin? Magnetic force
It can act without touching.

🚲 What helps bicycle brakes work? Frictional force
It opposes motion.

🏋️ What force lifts a bag by hand? Muscular force
Our muscles provide the force.

🎈 Why can a rubbed balloon attract hair? Electrostatic force
Electric charges attract.

🏗️ What force does a crane apply? Mechanical force
A machine applies force to lift a load.

🕵️ Force Detective Challenges

Case 1: A goalkeeper catches a moving football. What effect of force is shown?

The goalkeeper's force stops the moving football.

Case 2: A potter presses clay into a bowl. What effect of force is shown?

The applied force changes the shape of the clay.

Case 3: A batsman hits a moving ball towards the boundary. What can the force change?

The force can change the ball's speed and direction.

Case 4: Two children push a box equally from opposite sides. What kind of forces act?

Balanced forces act if the pushes are equal and opposite.

🧪 Try This Safe Home Activity

Paper, Cloth and Smooth Table Friction Test

You need: a toy car or eraser, a sheet of paper, a piece of cloth and a smooth table.

1. Give the object a gentle push on the smooth table.
2. Repeat with paper under it.
3. Repeat with cloth under it.
4. Observe where the object travels farthest and shortest.
5. Explain the result using friction.

Expected idea: A rougher surface usually creates more friction and stops the object sooner.

🔍 Do Not Confuse These

Mass

Mass tells us how much matter an object contains. It is commonly measured in kilograms (kg).

Weight

Weight is the gravitational force acting on an object. Force is measured in newtons (N).

PUSH or PULL can START, STOP, SPEED UP, SLOW DOWN, TURN or RESHAPE!

❓ Frequently Asked Questions

What is force for Class 6?

Force is a push or pull that can change, or try to change, the motion, direction, speed, shape or size of an object.

What are the main effects of force?

Force can start or stop motion, change speed, change direction and change the shape or size of an object.

What are contact forces?

Contact forces act when objects touch. Muscular force, frictional force and mechanical force are common examples.

What are non-contact forces?

Non-contact forces act without direct physical contact. Gravitational, magnetic and electrostatic forces are examples.

What is the SI unit of force?

The SI unit of force is the newton, written with the symbol N.

What is the difference between balanced and unbalanced forces?

Balanced forces are equal and opposite, so they do not change motion. Unbalanced forces produce an overall force and can change motion.
