## FAQs on Motion and Its Types (3) Video Lecture - Science Class 6

 1. What is motion and how is it defined?
Ans. Motion is the change in the position of an object with respect to its surroundings over time. It can be defined as the movement or displacement of an object from one place to another.
 2. What are the different types of motion?
Ans. There are three main types of motion: 1. Translational motion: This type of motion refers to the movement of an object in a straight line, where all parts of the object move the same distance and direction. 2. Rotational motion: This type of motion refers to the movement of an object around a fixed axis, where different parts of the object move through different distances and directions. 3. Vibrational motion: This type of motion refers to the back-and-forth movement of an object around a fixed position, where the object oscillates or vibrates.
 3. What is the difference between speed and velocity?
Ans. Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures the speed and direction of an object's motion. Speed does not take into account the direction of motion, whereas velocity considers both speed and direction.
 4. Can an object be in motion even if it is not changing its position?
Ans. Yes, an object can be in motion even if it is not changing its position. This is known as motion relative to another object or frame of reference. For example, if you are sitting in a moving car, you may not be changing your position with respect to the car, but you are still in motion with respect to the road or other stationary objects outside the car.
 5. How is motion measured?
Ans. Motion is measured using various parameters such as displacement, velocity, and acceleration. Displacement measures the change in position of an object, velocity measures the rate at which an object's position changes, and acceleration measures the rate at which an object's velocity changes over time. These measurements can be obtained using tools like rulers, timers, and motion sensors.
