Answer 1

Match the following :

1. A bird sitting on a tree $\longrightarrow$ Position of rest

$\longmapsto$ When the body is not changing its position with respect to a reference point, then it is called that the body is at rest. A bird sitting on a tree is not changing its position with respect to the reference point, so it is at rest.

2. Speed $\longrightarrow$ Scalar Quantity

$\longmapsto$ Scalar quantities are those quantities which have only magnitude. Speed has only magnitude, thus it a scalar quantity.

3. Vector $\longrightarrow$ Velocity

$\longmapsto$ Vector quantities are those quantities which have magnitude as well as direction. Velocity has both magnitude and direction, thus it a vector quantity.

⠀⠀____________________

1. Things we can see, touch and feel $\longrightarrow$ Object

$\longmapsto$ Objects are non-living things that we can see, touch and feel. Example : Chair, table and so on.

2. A fixed point in the neighbourhood $\longrightarrow$ Reference point

3. Point (0,0) $\longrightarrow$ Origin
