💡 Analysis & Explanation

[Classical Mechanics Principles] ▼

Isaac Newton's foundational Second Law of Motion mathematically links force, mass, and acceleration through the universal equation: Net Force (F) = mass (m) × acceleration (a).

[Velocity Analytics] ▼

The critical phrase in the question is 'uniform velocity'. A uniform (constant) velocity physically means that the speed and direction of the object are not changing over time.

[Acceleration Deduction] ▼

Because acceleration is strictly defined as the rate of change of velocity, an unchanging velocity results in an acceleration of exactly zero (0 m/s²).

[Final Computation] ▼

Substituting these values into Newton's equation: F = 10 kg × 0 m/s² = 0 Newtons. The mass is essentially irrelevant.

Conclusion ▼

The absolute net force acting on the body is 0 N.
