physics

The quantities having both magnitude and direction

• scalar quantity

• vector quantity

• constants

• variable quantity

Rate of change of distance is called

• velocity

• speed

• displacement

• acceleration

the quantity of motion contained in an object is called

• distance

• displacement

• force

• momentum

The SI unit of momentum

• m/s

• kgm/s

• m

• none

An object moves with constant speed of 5 m/s along the circumference of a circle .Then

• acceleration is zero

• acceleration is positive

• velocity is zero

• None

If an object covers equal distance in equal intervals of time .then its motion is said to be

• uniform

• nonuniform

• accelerated

• decelerated

unit of retardation is

• m/s

• m/s²

• m

• none

The slope displacement-time graph gives

• speed

• velocity

• acceleration

• distance

Area under velocity -time graph gives

• speed

• acceleration

• distance

• displacement

The inability of an object to change its state is called

• momentum

• acceleration

• inertia

• friction
