Question

For an object that has positive constant acceleration what does the speed vs time graph look like

Answer 1

The graph look like a line with positive slope and y-intercept equal to zero.

Step-by-step explanation:

Acceleration (a) is defined as follows:

a = v/t

where v refers to speed and t refers to time.

Isolating speed in the equation we get:

v = a*t

With a positive constant acceleration, this is the equation of a line with v as dependent variable, t as independent variable, and a as positive slope, which passes through coordinate (0, 0).

Answer 2

For an object with positive acceleration, the graph is a straight line but it has a slope. The graph is made between speed (on x-axis) and time (on y-axis). The diagram is attached.

Note:

1. If the slope of the graph is high i.e. steep graph, it means the acceleration is very high.
2. If the slope of the graph is low, it means the acceleration is less.
