A body is moving with a constant velocity. What is the net force acting on it?
medium Q8 of 15
Step-by-Step Solution
Step 1: Recall Newton's First Law
If velocity is constant, acceleration is zero, so net force must be zero.Step 2: Analyze options
Only zero net force corresponds to constant velocity. Mass × velocity is momentum, not force. Mass × acceleration is force but acceleration is zero here.Final Answer:
Zero → Option AQuick Check:
Net force = mass × acceleration = 0 when velocity constant ✅
Quick Trick: Constant velocity means zero acceleration and zero net force.
Common Mistakes:
MISTAKES- Confusing velocity with acceleration or force.
