Maharashtra State Board Class 6 Science Motion and Types of Motion Textbook Exercises and Extra Question and Answers.  

 

Identify the types of motion.

1. Movement of the earth around the sun: Circular motion
2. Movement of a ceiling fan: Circular motion
3. A meteor falling from the sky: Linear motion
4. A rocket launched from the ground: Linear motion
5. A fish swimming in water: Random motion
6. The plucked string of a sitar: Oscillatory motion

Fill in the blanks.

1. If a ball is released from the terrace of a building, it comes down in linear motion. On the other hand, it reaches the ground in non-linear motion if it is thrown with force away from the terrace in a direction parallel to the terrace.
2. The motion of an aeroplane on the runway before take-off is linear.
3. The kite looking for its prey flies with circular motion in the sky.
4. Children sitting in a rotating giant wheel have circular motion, while those sitting in a merry-go-round have non-linear motion.

Difference Between

Oscillatory motion and linear motion:

Oscillatory motion	linear motion
Oscillatory motion involves repetitive back-and-forth motion around a central point or along a fixed path. It is the pendulum of a clock or the strings of a guitar.	Movement along a straight line is called linear motion. There is no forward and backward movement in it. An object moving on the road or a ball falling from a building are examples.
In Oscillatory motion, the object often returns to its original point or position.	In linear motion, the object moves in the same direction without returning to the starting point.

Linear motion and random motion:

Linear motion	random motion
Linear motion is motion along a straight line or path, where the object moves in a specific direction and follows a predictable path.	Random motion is motion that lacks a specific direction or path. It is unpredictable and can involve an object moving in different directions without following a pattern.
Linear motion can be described with equations and is often more controlled and predictable.	Random motion is characterized by its lack of predictability and may be influenced by various factors.

Random motion and oscillatory motion:

Random motion	oscillatory motion
When a motion can change its direction unexpectedly, it is random motion.	Oscillatory motion involves repetitive back-and-forth motion around a central point or along a fixed path.
Random motion is irregular and has no rules.	The oscillatory motion is continuous and follows a fixed pattern, with the object returning to a fixed point or position after each rotation.

Explain in your own words, giving one example each.

Linear Motion:

When an object moves in a straight line, it is in linear motion. This means that the object changes its position from one point to another in the same direction without deviating. An example of linear motion is a car driving on a straight road. It shows linear motion as the car moves from one end of the road to the other without turning.

 

Oscillatory Motion:

An object rotating back and forth around a central point or along a fixed path is oscillatory motion. It does the same trick over and over again. The swinging pendulum on a clock is a simple example of oscillatory motion. The pendulum returns to its original position with every swing.
