What is Force?

A force is a push or a pull that can make an object:✔ Move or stop moving✔ Change speed✔ Change direction✔ Change shape

Force is measured in Newtons (N) and is applied on matter (solid, liquid, or gas).

What is Matter?

Matter is anything that has mass and takes up space. It exists in three states:🔹 Solid – Fixed shape and volume🔹 Liquid – Fixed volume but takes the shape of its container🔹 Gas – No fixed shape or volume

When a force is applied to matter, it can change its motion or shape.

Forces Acting on Solids

When a force is applied to a solid object, it may:✅ Stay the same if the force is too small✅ Move if the force is strong enough✅ Change shape by bending, stretching, or compressing

🔹 Example: When you push a box, it moves in the direction of the force.

Stretching and Extension of a Spring

When a force is applied to a spring, it stretches. The more force you apply, the more the spring extends.

If you stop applying force, the spring returns to its original shape (if within the elastic limit).

🔹 Example: Pulling a rubber band—it stretches when pulled and returns when released.

✔ Jumping on a trampoline – The surface bends and returns to its original shape.✔ Pressing a sponge – It gets compressed but expands back.✔ Pulling a rubber band – It str
