FAQs on Quick Revision: Motion and Time Video Lecture - Science Class 7

1. How does motion relate to time?
Ans. Motion and time are closely related as motion involves the change in position of an object over a specific period of time. Time is a crucial factor in measuring various aspects of motion such as speed, acceleration, and distance traveled.
2. Can motion exist without time?
Ans. Motion cannot exist without time as motion is defined by the change in position of an object over a period of time. Without time, there would be no way to measure or quantify the movement of an object.
3. How does time affect the speed of an object in motion?
Ans. Time plays a crucial role in determining the speed of an object in motion. Speed is calculated as the distance traveled by an object divided by the time taken to travel that distance. Therefore, the time taken directly impacts the speed of an object.
4. Is there a relationship between time and the acceleration of an object?
Ans. Yes, time is directly related to the acceleration of an object. Acceleration is the rate of change of velocity over time. Therefore, the time taken for an object to change its velocity affects its acceleration.
5. How does the concept of time impact the concept of relative motion?
Ans. Time is a crucial factor in determining the relative motion between two objects. The difference in time measurements between the two objects can affect how their motion is perceived relative to each other.
