A force of 10 N acts on an object causing it to accelerate at 2 m/s². What is the mass of the object?

To determine the mass of the object, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). In this scenario, we know the force (10 N) and the acceleration (2 m/s²).

We can rearrange the formula to solve for mass (m):

m = F / a

Substituting the known values into this equation gives us:

m = 10 N / 2 m/s² = 5 kg

Thus, the mass of the object is 5 kg. This result shows that the relationship between force, mass, and acceleration is a foundational concept in physics and is crucial for solving similar problems.
