Introduction
All objects if not all, change their speed over time. This rate of change of speed is called acceleration.
Pre-Requisites:
Basic Idea about motion,Velocity (speed with direction)
Activity:
Race Statistics- it gives you the analysis of acceleration (and deceleration) and speed at various points.
Real Life Question:
If a runner from rest reaches a speed of 3m/s in 2 seconds, what is the acceleration?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Acceleration | The rate of change of velocity with time |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Graph Paper | From a velocity time graph, determine the acceleration of a body |
Real life uses :
In Auto mobiles, air and water vehicles to start, stop and vary the speed and is the requirement and achievable.
Practical examples around us
| Examples | Explainations |
|---|---|
| Transport | All vehicles have to accelerate and decelerate to achieve different speeds, start and stop. |
What you learn in Theory:
The concept of acceleration and how it relates to the velocity.
What you learn in Practice:
How we encounter acceleration in everyday life and the importance of its analysis in various applications.
