Motion class 9

what is reference point?

• navigation tool

• google maps another version

• a point used for describing the location of object

• a point used for describing the looks of object

what is origin?

• the place where something starts from.

• something from where it has originated.

• reference point used for describing any place.

• reference point used for describing the location of the object.

what is motion?

• change of position of object.

• change of speed of object.

• change of shape of object.

• change of size of object.

Rectilinear motion is:

• object moving on curved path

• object moving on straight path

• object moving on a rectangle

• object moving on a square

What is distance?

ans. Distance is:

• shortest length covered by the object from the initial point till the ending point.

• largest length covered by the object from the initial point till the ending point.

• assumption of how much length the object may cover.

• actual length covered by the object from the initial till the ending point.

what is displacement?

ans. Displacement is:

• shortest length covered by the object from the initial point till the ending point.

• largest length covered by the object from the initial point till the ending point.

• assumption of how much length the object may cover.

• actual length covered by the object from the initial till the ending point.

Displacement can be:

• Zero

• more than Distance

• equal to Distance

• negative

Distance is never:

• negative

• positive

• less than displacement

• more than displacement

• Zero

distance is:

• vector quantity

• nothing

• scalar quantity

• everything

displacement is:

• vector quantity

• nothing
