Answer: Matter

Matter is anything that has mass and occupies space. It is made up of tiny particles called atoms and molecules. There are three states of matter: solid, liquid, and gas.

Matter can be classified into two types:

Pure substances: substances that have a fixed composition and definite properties. Examples of pure substances include elements (e.g., gold, silver) and compounds (e.g., water, salt).
Mixtures: substances that are composed of two or more pure substances. Examples of mixtures include air, seawater, and soil.
Matter can also be classified based on its physical and chemical properties.

Physical properties:
Color
Odor
Taste

Chemical properties:
Reactivity
Combustibility
Solubility

One Mark Question and Answers (Force and Laws of motion )
1. Define momentum

👉 Momentum of an object is the product of its mass and velocity.
Momentum = 𝑚 × 𝑣
where:
𝑚 is the mass and
𝑣 is the velocity.
Unit: kg·m/s.

2. State first law of motion.

👉 Newton’s First Law of Motion states:
"An object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction, unless acted upon by an external force."

3. What is Inertia?

👉Inertia is the tendency of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

4. Can action and reaction balance each other?

👉No, action and reaction forces do not balance each other because they act on different objects. They are equal in magnitude but opposite in direction.

5. How does one climb up a rope?

👉To climb a rope, you pull the rope downward, and the rope exerts an upward force (reaction) on your body, helping you lift yourself up.
