Newton's Second Law of Motion (Law of Acceleration) - JSS2 Basic technology Lesson Note
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed with the formula: \( F = ma \), where \( F \) is the net force, \( m \) is the mass, and \( a \) is the acceleration.
This law tells us that the greater the force applied to an object, the greater its acceleration. However, the more massive the object, the less it accelerates in response to the same force.
Practical Examples:
- Pushing a car requires more force than pushing a bicycle to achieve the same acceleration because the car has more mass.
- A soccer ball accelerates more when kicked with a greater force.
