Identifying types of motion in Motion and Time – Class 7 Science Experiment
Chapter Name: Motion and Time
Activity Name: Identifying types of motion in Motion and Time
Activity Description:
In this activity, we will observe various motions and categorize them as rectilinear, curvilinear, or both (rectilinear and curvilinear).
Required Items:
- Seconds hand of a watch
- Model train on tracks
- Tape recorder with a tape
- Car with a speedometer
- Bus on a hill station road
- Carrom board with coins
- Pin board with a ball
- A mango
Step by Step Procedure:
- Examine each of the given items separately.
- Observe their motion carefully.
Experiment Observations:
- Now, let’s label the motions as rectilinear (R), curvilinear (C), or rectilinear and curvilinear (RC) based on our observations:
- Seconds hand of a watch. ( C )
- Movement of a train on tracks. ( R )
- Movement of a tape in a tape recorder. ( R )
- Movement of a needle in a speedometer of a car. ( C )
- Movement of a bus on a hill station road. ( C )
- Motion of coins on a carrom board. ( R )
- Motion of the ball in a pin board. ( C )
- Motion of a mango falling from a tree. ( C )
Precautions:
- Handle the items with care, especially the fragile ones like the tape recorder and the mango.
- Ensure a safe environment for conducting the activity.
Lesson Learnt from Experiment:
Through this experiment, we learned about different types of motion – rectilinear motion, which follows a straight path, and curvilinear motion, which follows a curved path. Some objects, like the seconds hand of a watch, can exhibit curvilinear motion as well as some rectilinear components. It’s important to keenly observe and understand the nature of motion for various objects in our daily lives.
