Question

Name the physical quantities measured by

(a) areaunder v -t graph

(b) slope of s-t graph

(c) slope of v -t graph
​

Answer 1

Answer:

a)The area under velocity vs time graph gives fundamental physical quantity called displacement. The velocity time graph is a straight line graph of the form y = mx+c , where c is the intercept and m is the defined slope of the graph.

b) Graphs look much like Distance-Time graph. Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis A straight horizontal line on a speed-time graph means the speed is constant.

c)The slope of speed and time graph gives the magnitude of acceleration. The slope of speed and time graph gives the magnitude of acceleration.
