quiz on scalar and vector physical quantities

Area under graph of velocity-time tells us

• displacement

• speed

• distance covered

Equation of motion can be used for-

• straight line motion only

• curved motion only

• motion along a circular path

• all types of motion

The slope of distance-time graph is-

• distance

• accelaration

• speed

• displacement

Distance covered by a body from velocity-time graph is

• equal to the slope under graph

• area of the graph

• is denoted by line parallel to time axis at any point on the distance axis.

• is denoted by line parallel to distance axis at any point on the time axis.

The S.I unit of acceleration is-

Which one is the correct slope of velocity-time graph ?

• v+ut

• u+vt

• v-u/t

• u-v/t

If the velocity-time graph is not in the straight line,then its accelaration is-

• Variable

• Positive

• Negative

• Zero

If Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speed of 10 ms-1 It implies that the boy is

• at rest

• moving with no acceleration

• in accelerated motion

• moving with uniform velocity

A body is projected vertically upward from the ground. Taking vertical upward direction as positive and point of projection as origin, the sign of displacement of the body from the origin when it is at height h during upward and downward journey will be

• Positive, positive

• Positive, negative

• Negative, negative

• Negative, positive

According to the given velocity-time graph, the object

• is moving with uniform velocity

• has some initial velocity

• is moving uniformly with some initial velocity

• is at rest
