Sure! Here is a sample test for motion and time, specifically for Class 7 students studying Science. This test will help students assess their understanding of the topic and prepare for their Term-1 examination.

Test: Motion and Time

Section A: Multiple Choice Questions

1. Which of the following is an example of circular motion?
a) A car moving in a straight line
b) A pendulum swinging back and forth
c) A ball rolling down a hill
d) A person walking in a park

2. The SI unit of time is:
a) Meter
b) Kilogram
c) Second
d) Newton

3. What is the distance covered by an object per unit time called?
a) Speed
b) Velocity
c) Acceleration
d) Distance

4. Which of the following is an example of uniform motion?
a) A car accelerating from rest
b) A ball rolling down a hill
c) A person running in a marathon
d) A bicycle moving at a constant speed

5. If an object covers a distance of 200 meters in 20 seconds, what is its average speed?
a) 4 m/s
b) 8 m/s
c) 10 m/s
d) 20 m/s

Section B: Short Answer Questions

1. Define motion.
2. What is the difference between speed and velocity?
3. Explain the term 'acceleration' with an example.
4. What is the difference between uniform motion and non-uniform motion?
5. Calculate the speed of a car that travels a distance of 500 meters in 25 seconds.

Section C: Long Answer Question

1. A car takes 2 hours to travel a distance of 240 kilometers. Calculate its average speed.

Solution:

Section A: Multiple Choice Questions
1. b) A pendulum swinging back and forth
2. c) Second
3. a) Speed
4. d) A bicycle moving at a constant speed
5. c) 10 m/s

Section B: Short Answer Questions
1. Motion is the change in position of an object with respect to its surroundings.
2. Speed is the distance covered by an object per unit time, while velocity is the displacement of an object per unit time along with its direction.
3. Acceleration is the rate at which the velocity of an object changes with time. For example, when a car speeds up or slows down, it is experiencing acceleration.
4. Uniform motion is when an object covers equal distances in equal intervals of time, while non-uniform motion is when an object covers unequal distances in equal intervals of time.
5. Speed = Distance/Time
Speed = 500 meters / 25 seconds
Speed = 20 m/s

Section C: Long Answer Question
1. Average speed = Total distance / Total time
Average speed = 240 kilometers / 2 hours
Average speed = 120 km/h

By answering this sample test, students can assess their knowledge and understanding of motion and time. It covers various aspects of the topic, including definitions, calculations, and differentiating between different types of
