Physics-Uniform & Non-uniform Motion
NEET Physics Uniform & Non-uniform Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following combinations correctly describes uniform and non-uniform motion?
A
In uniform motion, acceleration is zero; in non-uniform motion, acceleration varies.
B
Uniform motion can have varying speeds; non-uniform motion always has constant speed.
C
Uniform motion is characterized by a parabolic x-t graph; non-uniform motion has a straight line x-t graph.
D
In non-uniform motion, the velocity-time graph is straight; in uniform motion, it is curved.
Correct Answer
Option A
Detailed Explanation
Uniform motion has zero acceleration, resulting in a straight line on the x-t graph, while non-uniform motion is characterized by varying acceleration, which can lead to curves. This aligns with the definitions in the NCERT context.
