A block of dry ice slides at a constant velocity on a smooth,
horizontal, frictionless surface. A second block of dry ice
slides twice as fast on the same surface (at a higher constant
velocity). Compare the resultant forces exerted on each block.
Explain your reasoning.

Key Concepts

Newton's First Law of Motion

This law states that an object will maintain its state of rest or uniform motion in a straight line unless acted upon by a net external force. In the context of constant velocity motion, it implies that if an object is moving at a constant velocity (i.e., without acceleration), there is no net force acting on it.

Relationship Between Net Force and Acceleration (Newton's Second Law)

Newton's Second Law establishes that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). When an object is moving at a constant velocity, its acceleration is zero, which means the net force must be zero regardless of its speed.
