Introduction
Velocity is a vector
quantity that needs to be described using the speed of the particle and the
direction of motion of the particle.
Pre-Requisites:
Vector Resolution,
Position Vector, Displacement, Displacement Vector, Velocity
Activity:
Observe and
understand why two cars travelling in the same speed but in opposite directions
are said to have different velocities
Real Life Question:
Which vector quantity
defines both speed and direction of a particle?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Velocity | Velocity is a vector quantity that has both speed and direction. |
| Average Velocity | Displacement of a body over a fixed time interval is called Average Velocity. |
| Instantaneous Velocity | The velocity of a body at any particular instant. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Race | To observe velocity |
Real life uses :
Can
help us to analyse the motion of bodies mathematically
Places to visit :
Car race
Practical examples around us
| Examples | Explainations |
|---|---|
| Vehicles | Different vehicles travel with different velocities. |
What you learn in Theory:
Analysis of velocity
using vectors and calculus
What you learn in Practice:
How velocity is quite
different from speed and that direction of a body is as important as the speed
when defining the motion of a body
