Motion types in Motion and Time – Class 7 Science Experiment
Chapter Name: Motion and Time
Activity Name: Motion types in Motion and Time
Activity Description:

In this experiment, we will observe the motion of different bodies and classify them into three categories: Rotatory (R), Translatory (T), and Translatory and Rotatory (TR). The objective is to understand the different types of motion exhibited by objects.
Required Items:
- Various objects (e.g., a spinning top, a car, a rolling ball, a swinging pendulum, etc.)
Step by Step Procedure:
- Set up the experiment by gathering the objects that will be used to demonstrate different types of motion.
- Ensure that you have a clear and open space to allow the objects to move freely.
- Perform the following observations one by one: a. Observe the motion of the spinning top. b. Observe the motion of the car as it moves on a flat surface. c. Observe the motion of the rolling ball. d. Observe the motion of the swinging pendulum. e. Observe any other relevant object with distinct motion.
Experiment Observations:
- Spinning top – Rotatory (R)
- Car on a flat surface – Translatory (T)
- Rolling ball – Translatory and Rotatory (TR)
- Swinging pendulum – Translatory and Rotatory (TR)
- [Any other object] – [Classify its motion]
Precautions:
- Ensure the objects used in the experiment are safe and do not cause any harm.
- Keep the experimental area clear to avoid any obstructions during the observations.
- Handle the objects carefully to maintain their integrity and functionality.
Lesson Learnt from Experiment:
Through this experiment, we learned that different objects exhibit different types of motion. Some objects display pure rotational motion (R), where they spin about a fixed axis, while others show translational motion (T), where they move along a straight path.
Additionally, some objects display a combination of both rotational and translational motion (TR), like the rolling ball and swinging pendulum. The experiment highlights the diversity of motion types that can be observed in various objects.
