Question

The following graphs represent the velocity-time graph. Identify what kind of motion a particle undergoes in each graph.

(a)
(b)
(c)
(d)

Answer 1

(a) At all the points, the slope of the graph is constant.
∴ `veca` = constant

(b) No change in magnitude of the velocity with respect to time
∴ `vecv` = constant

(c) Slope of this graph is greater than graph (a) but constant
∴ `veca` = constant but greater than the graph (a)

(d) At each point-slope of the curve increases.
∴ `veca` is a variable and the object is in accelerated motion.
