Answer:

ACCELERATION FROM VELOCITY-TIME GRAPH - RESULT

concept

Acceleration of a particle is equal to the slope of a velocity-time graph.

a=

t

2

−t

1

v

2

−v

1

In the given graph,

a=

4−2

40−20

=10 m/s

2

Acceleration may be positive, negative or zero as it is a vector quantity.

VELOCITY-TIME GRAPH - DEFINITION

concept

The Velocity Time Graph: Velocity-time graph is a plot between Velocity and Time. It shows the Motion of the object that moves in a Straight Line. Magnitude of Velocity at a given instant is equal to its Instantaneous Speed. It is drawn for 1-D motion only and can take both positive and negative values.

In case where the acceleration is zero, tthe slope is zero ( horizontal line). If the acceleration is positive, then the slope is positive (an upward sloping line).
