M = 2 kg
g = 9.8 m/s^2
Multiply them. The answer will be in Newtons.
To calculate the force acting on a falling mass, you need to consider two important forces: the force due to gravity and the force caused by air resistance (or drag).
1. Force due to gravity: The force of gravity acting on an object can be calculated using Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by the acceleration due to gravity (g). In this case, the mass is 2 kg, and the acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the force due to gravity is calculated as follows:
F_gravity = m * g
= 2 kg * 9.8 m/s^2
= 19.6 N
The force due to gravity acting on the 2 kg mass is 19.6 Newtons (N).
2. Force of air resistance (drag): The force of air resistance or drag depends on several factors, such as the shape and size of the object, its speed, and the properties of the surrounding fluid. Without specific details, it is difficult to calculate the exact force of air resistance. However, for most typical situations, we can assume that the force of air resistance is negligible for the falling of a 2 kg mass. Therefore, we can ignore it for this calculation.
Hence, the force acting on a falling 2 kg mass is primarily the force due to gravity, which equals 19.6 Newtons (N).
