CBSE Class 7 Science Chapter 9 Motion and Time Worksheets

The “Motion and Time” Chapter 9 of the CBSE Class 7 Science syllabus consists of an introduction to motion and time, including how things around us move, different types of motion, how to measure time using clocks, and how to calculate speed and distance using distance-time graph. Understanding these topics gives students a thorough introduction and helps clear their concepts for exams. 

Different types of motion, how to measure time using clocks, and how to calculate speed and distance. It also explains how to draw and read distance-time graphs, which is super helpful for understanding how fast or slow an object is moving. 

If one will solve Motion and Time worksheets daily then students easily get to know how to solve questions in exam. It helps to improve accuracy, understand formulas better. Regular practice makes topics like speed = distance/time and graph reading much easier to remember.

What is Motion and Time?

Motion and Time are two very important concepts in science. Motion means the movement of an object from one place to another. For example, when a car moves on the road or a fan rotates, both are showing motion. Anything that changes its position with time is said to be in motion.

Time helps to measure how long something takes to happen. It tells us the duration of motion or how fast or slow an object is moving. Without time, it would be impossible to compare movements or calculate speed. 

Understanding motion and time means seeing science in real life from running in the playground to watching vehicles on the road.

C. Short Answer Questions (2 marks each)

1. Define motion.
   Motion is the change in position of an object with time.
2. What is the difference between uniform and non-uniform motion?
   In uniform motion, equal distances are covered in equal intervals of time. In non-uniform motion, distances covered are unequal.
3. Name any two devices used for measuring time.
   Clock and stopwatch.
4. What does the area under a distance-time graph represent?
   It represents the distance travelled.

D. Formula-Based Numericals (3 marks each)

1. A car travels 240 km in 4 hours. Find its speed.
   Speed = Distance ÷ Time = 240 ÷ 4 = 60 km/h
2. A cyclist covers 45 km at a speed of 15 km/h. Find the time taken.
   Time = Distance ÷ Speed = 45 ÷ 15 = 3 hours
3. A train moves at 90 km/h. How far will it go in 2.5 hours?
   Distance = Speed × Time = 90 × 2.5 = 225 km
4. Convert 10 m/s to km/h.
   10 × 3.6 = 36 km/h
