Here's why:
* Newton's Second Law of Motion: This law states that the force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a). The equation is: F = m * a
* To find the force: You need both the mass (m) and the acceleration (a). You've provided the acceleration (1 m/s²), but you need the mass to use the formula.
Example:
Let's say the mass of the object is 5 kg. Then:
* F = m * a
* F = 5 kg * 1 m/s²
* F = 5 Newtons (N)
Therefore, to determine the force, you need to provide the mass of the object.
