Question

The displacement-time graph of a moving body is a straight line making a 45\(^{\circ}\) angle with the time axis. The body moves with:

• A. uniform velocity
• B. uniform acceleration
• C. non-uniform acceleration
• D. decreasing velocity
• E. increasing velocity

Hint:

The slope of a displacement-time graph represents velocity. A constant slope means uniform velocity.

Answer 1

The Correct Option is A

A displacement-time graph with a straight-line pattern implies that the rate of change of displacement remains constant, 
meaning:  \[ \text{velocity is constant.} \]Since velocity is uniform, acceleration must be zero, ruling out options involving acceleration.
