Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 6 - No. 32)
If the acceleration is constant, what does the speed-time graph look like?
A horizontal line
A straight line with a non-zero slope
A straight line with zero slope
A curved line
Vysvětlení
Constant acceleration means the speed changes at a constant rate, so the graph is a straight line with a non-zero slope.
