When two organisms share their shelter and food, this process is known as symbiosis.

Test for Matter in Our Surroundings

To determine whether something is a matter or not, we can conduct a test known as the Matter Test. This test involves observing and analyzing the physical properties of an object to determine if it is a matter or not.

Physical Properties of Matter

Physical properties of matter are characteristics that can be observed or measured without changing the substance's identity. Some of the physical properties of matter include:

- Mass
- Volume
- Density
- Color
- Texture
- Odor
- Melting point
- Boiling point

3. The rate of change of velocity is called:
a) Speed
b) Acceleration
c) Distance
d) Displacement

Answer: b) Acceleration

4. The distance covered by a body in unit time is called:
a) Speed
b) Velocity
c) Acceleration
d) Distance

Answer: a) Speed

5. A body is said to be in uniform motion if:
a) Its speed is constant
b) Its velocity is constant
c) Its acceleration is constant
d) Its displacement is constant

Answer: a) Its speed is constant

Conclusion

Conducting the matter test can help us determine whether something is a matter or not. Physical properties of matter like mass, volume, density, color, texture, odor, melting point, and boiling point can be observed and analyzed to determine if something is a matter or not. MCQs on motion can help students test their knowledge of basic concepts related to motion.
