//Multiple Choice

Object moving in a circle is said to perform-
{
= Linear motion
~ Circular motion
~ Oscillatory motion
~ Harmonic motion
}

When a giant-wheel moves half a rotation, the distance and displacement of a person sitting in the wheel is
{
= equal
~ zero
~ distance > displacement
~ distance < displacement
}

When a giant-wheel moves half a rotation, the displacement of a person sitting in the wheel is
{
= equal to diameter of the wheel
~ equal to radius of the wheel
~ zero
~ double of diameter of the wheel
}

Birds flying is an example of
{
~ speed
~ distance
= motion
~ velocity
}

If an object changes its position with respect to time, it is said to be in
{
= motion
~ distance
~ acceleration
~ lake
}

Distance traveled by an object in motion can
{
~ always be zero
= never be zero
~ never be calculated
~ none of these
}

When you are travelling by a train, the person sitting next to you is
{
= stationary
~ moving
~ in motion
~ driving
}

For a girl, standing on a platform, the passengers sitting in a train are
{
~ stationary
= in motion
~ stopped
~ none of these
}

//True or False

Displacement can never be zero. {F}

Magnitude of displacement is always less than or equal to distance. {T}

The motion of an object is not defined with respect to a reference point. {F}

An object moving in a circle is said to perform linear motion. {F}

If an object changes its position with respect to time, it is said to be stationary. {F}

Displacement is the shortest distance between initial and final position. {T}

Displacement of a runner on completing one round of circular track is zero. {T}

Birds flying is said to be in motion. {T}

Girl standing on road is said to be in motion. {F}

When initial point and final points are same, then displacement is zero. {T}



//Match the Following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Distance -> Total path traveled
=Net Displacement -> Can be zero
=Straight-line motion -> Linear motion
=Motion -> Change in position
=Displacement -> Shortest path
}

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Total distance traveled -> The sum of all path lengths
=Not moving -> stationary
=SI unit -> meter
=Displacement in half circle -> diameter
=Reference point -> origin
}
