Question

7. The velocity – time graph of an object is shown in the following figure

a. State the kind of motion that the object has from A to B

b. Identify the part of graph where the object has zero acceleration. Give reason

for your answer. answer

c. Identify the part of the graph where the object has negative acceleration. Give

reason for your answer. ​

Answer 1

(a) Uniform motion from A to B and non-uniform motion from B to C.

(b) AB because velocity remains constant from A to B.

(c) BC because velocity decreases from B to C.

Hope it is helpful

Answer 2

Answer:

a) uniform motion

b) A to B since velocity is constant therefore

change in velocity i.e. acceleration is zero

c) it's from C to D since velocity is decreasing here
