Question

Activity: Plot the following graph in graph paper :
a. Displacement time graph.
b. Velocity time graph
Of your data and paste them in HW.copy by writing details , Aim, materials , required and Learning outcomes.

​

Answer 1

Answer:

concept

Velocity of a particle is equal to the slope of its displacement-time graph.

v=

t

2

−t

1

s

2

−s

1

In the given graph,

v=

4−2

40−20

=10 m/s

Velocity may be positive, negative or zero since it is a vector quantity.

Note: When we draw graph of a vector (say displacement), each component (like component in x-direction) of the vector is drawn on a separate graph. So, for a 2-D motion, two graphs are needed to completely describe the motion of a particle.concept

A distance-time graph is a graph of distance v/s time. It lies in first quadrant only as distance is always positive. Also, it is increasing in nature. The attached plot shows a distance-time graph
