Identify different types of motions in Motion and Time – Class 7 Science Experiment
Chapter Name: Motion and Time
Activity Name: Identify different types of motions in Motion and Time
Activity Description:
In this activity, we will observe different objects and their motions to identify which ones exhibit oscillatory motion.
Required Items:
- Spinning top
- Bullet
- Typewriter key
- Potter’s wheel
- Sitar
- Car
- Bell
- Bouncing ball
Step by Step Procedure:
- Take all the required items listed above.
- Observe each item separately and carefully.
- Pay attention to the nature of their motion.
- Identify whether the motion of each item is oscillatory or not.
- Mark the items that exhibit oscillatory motion with () in the brackets provided.
Experiment Observations:
- A spinning top ()
- Bullet fired from a gun ( )
- Typewriter key ()
- Motion of a potter’s wheel ( )
- Motion of a vibrating sitar string ()
- Motion of a car taking a turn while moving ( )
- Ringing of a bell ()
- A bouncing ball ()
Precautions:
- Handle the objects carefully to avoid any accidents or damage.
- If applicable, ensure the spinning top and bouncing ball are used on appropriate surfaces to prevent any harm.
- Be cautious while observing moving objects to avoid injury.
Lesson Learnt from Experiment:
From this experiment, we learned that oscillatory motion is characterized by repetitive back-and-forth or to-and-fro movement around a central position. The objects that exhibited oscillatory motion were the spinning top, the typewriter key, the vibrating sitar string, the ringing bell, and the bouncing ball.
On the other hand, the bullet fired from a gun and the car taking a turn while moving did not show oscillatory motion. The motion of the potter’s wheel was not oscillatory either, as it involves continuous rotation rather than back-and-forth movement.
