Free Fall
Physics: Edexcel IGCSE, topic 1.3.12
Free Fall
If an object is in free fall, then the object’s weight is the only force acting on it. The weight of an object is the force that acts downwards on an object due to gravity.

Acceleration due to gravity
- An object in free fall will accelerate at a constant rate. This constant rate is called the acceleration due to gravity (g).
- The average value for acceleration on Earth due to gravity is 9.81 m/s2, but we round it up to 10 m/s2 in most calculations.
