Introduction
The force acting on an object of fixed mass is the product of mass and acceleration of the object. This can be obtained by formulating the Second Law of Motion.
Pre-Requisites:
Equations of Motion, Newton's Second Law, Motion
Activity:
Calculate the force of gravity acting on you (and other objects around) by considering the acceleration due to gravity, g.
Real Life Question:
What is the force applied to an object of 1kg mass accelerating at 10m/s~2?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Force | Rate of change of momentum; for an object of fixed mass, force is the product of mass and acceleration. |
Learning aids / Gadgets

Real life uses :
By having an idea of the sort of motion to be executed, the parameters (like acceleration) to be attained etc will give an idea about the amount of force that needs to be applied. All the motions or machineries are based on this fundamental concepts.

Practical examples around us
| Examples | Explainations |
|---|---|
| Transport | Every transport equipment requires a force to accelerate |
What you learn in Theory:
Mathematically, how the magnitude of force relates to the motion parameters like acceleration, velocity and inertial parameter, mass.
What you learn in Practice:
Application of this formulation to the practical problems around us.
