A v-t graph shows two straight lines: one with steep positive slope and one with gentle positive slope. The steeper line represents:
A.
Greater speed
B.
Greater acceleration
C.
Greater displacement
D.
Greater time
😑 View Answer Rough Work Error
ANSWER :

14.
On a v-t graph, an object has v = v₀ at t = 0 and v = 0 at t = t₁, with constant deceleration. The distance covered before stopping is represented by:
A.
Height of the triangle (v₀)
B.
Base of the triangle (t₁)
C.
Area of the triangle = ½v₀t₁
D.
Slope of the line = v₀/t₁
😑 View Answer Rough Work Error
ANSWER :
C. Area of the triangle = ½v₀t₁

A v-t graph has a kink (sharp corner) at some point. NCERT states this is physically unrealistic because:
A.
Acceleration would change abruptly (not continuously)
B.
Velocity cannot be measured there
C.
Area cannot be calculated
D.
The slope becomes infinite
