FAQs on Mindmap: Motion and Measurement of Distance - Science Class 6

 1. What is motion and how is it measured?
Ans. Motion refers to the change in position of an object with respect to its surroundings over time. It can be measured using various methods such as measuring the displacement, velocity, or acceleration of the object. Displacement is the change in position from the initial point to the final point, while velocity is the rate of change of displacement and acceleration is the rate of change of velocity.
 2. How is distance different from displacement?
Ans. Distance refers to the total length covered by an object, irrespective of its direction, while displacement is the change in position of an object from the initial point to the final point in a specific direction. Distance is a scalar quantity, whereas displacement is a vector quantity as it includes both magnitude and direction.
 3. What are the different units of distance measurement?
Ans. Distance can be measured using various units such as meters (m), kilometers (km), miles (mi), centimeters (cm), etc. The choice of unit depends on the scale of measurement and the convenience of expressing the distance in a particular context.
 4. How can the speed of an object be calculated?
Ans. The speed of an object can be calculated by dividing the distance traveled by the time taken. The formula for speed is: Speed = Distance / Time The unit of speed is typically expressed as meters per second (m/s) or kilometers per hour (km/h), depending on the context.
 5. What is the difference between speed and velocity?
Ans. Speed refers to the rate at which an object covers distance, whereas velocity refers to the rate at which an object changes its displacement. While speed only considers the magnitude, velocity considers both magnitude and direction. For example, if a car travels 50 km/h north, its speed will be 50 km/h, but its velocity will be 50 km/h north.
