Drawing path and distinguishing between distance and displacement in Motion – Class 9 Science Experiment
Chapter Name: Motion
Activity Name: Drawing path and distinguishing between distance and displacement in Motion
Activity Description:
In this experiment, you will observe the path of a ball thrown into the air at some angle to the horizontal and draw it on paper. The aim is to understand the concepts of “distance” and “displacement” in motion.
Required Items:
- Ball
Step by Step Procedure:
- Take a ball and throw it into the air at an angle to the horizontal.
- Observe the path followed by the ball as it moves through the air.
- On a piece of paper, draw the path of the ball as accurately as possible.
Experiment Observations:
- Figure 5 shows the path taken by the ball when it was thrown into the air.
Precautions:
- Ensure a safe environment for conducting the experiment, with enough space to throw the ball without any obstructions or hazards.
- Be cautious while throwing the ball to avoid any injuries to yourself or others.
- Use a soft ball or conduct the experiment in an area where the ball won’t cause damage upon landing.
Lesson Learnt from Experiment:
This experiment helps to understand the fundamental difference between distance and displacement. Distance is the total path length traveled by an object, while displacement is the straight-line distance and direction from the initial position to the final position. The concept of distance is a scalar quantity, whereas displacement is a vector quantity.
