Motion 
U N D E R S T A N D I N G S P E E D A N D M O T I O N C O N C E P T S
UNIFORM MOTION
In uniform motion, an object travels
equal distances over equal time
intervals.
Example: A car moving at 40 km/h
consistently.
NON-UNIFORM
Non-uniform motion involves varying
speed and changing distances over time
periods.
Example: A car moving in traffic with
varying speed.
TIME MEASUREMENT
Time is measured in seconds, minutes,
and hours for consistency.
 SI Unit of Time: Second (s)

FAQs on Infographics: Motion and Time - Science Class 7

1. What is the relationship between motion and time in physics?
Ans. Motion refers to the change in position of an object over time. In physics, time is a crucial parameter that helps quantify motion. The relationship can be expressed through equations of motion, where distance, speed, and time are interrelated. For example, the formula distance = speed × time illustrates how the distance traveled by an object is dependent on its speed and the time duration of travel.
2. How do we measure time in relation to motion?
Ans. Time in relation to motion is measured using various instruments like clocks and stopwatches. In physics experiments, precise timing is essential for calculating speed and acceleration. By recording the time taken for an object to travel a certain distance, one can determine its average speed or analyze its motion in detail.
3. What are the different types of motion discussed in relation to time?
Ans. The main types of motion discussed include linear motion, rotational motion, and oscillatory motion. Linear motion involves movement along a straight path, rotational motion involves spinning around an axis, and oscillatory motion is periodic movement, such as a pendulum swinging. Each type of motion can be analyzed in terms of how it changes over time.
4. How do graphs represent motion and time?
Ans. Graphs are a powerful tool for representing motion and time. A distance-time graph shows how distance changes over time, while a velocity-time graph illustrates how velocity varies with time. The slope of these graphs can provide insights into the speed and acceleration of the object, allowing for easier visualization and interpretation of motion.
5. Why is understanding motion and time important in real-world applications?
Ans. Understanding motion and time is crucial in various fields such as engineering, transportation, and sports. It helps in designing safer vehicles, optimizing travel routes, and improving athletic performance. Moreover, principles of motion and time are fundamental in scientific research and technology development, ensuring efficiency and accuracy in various applications.
