Newton's First Law
Easyphysics
A block of mass 2 kg is placed on a frictionless horizontal surface. If no external force acts on it, what can be said about its motion?
Select the correct option:
Solution
Incorrect! Answer:
It will continue in uniform motion
- Newton's First Law: States that every body continues in its state of rest or of uniform motion in a straight line unless it is compelled by some external force to change that state.
- Analysis:
- The surface is frictionless, so there is no resistive force.
- No other external forces are applied.
- Result: The net force ∑F=0.
- Conclusion: According to the Law of Inertia, the block will maintain its current velocity (uniform motion) forever.
