which of the following physical quantities are considered as scalar only?

• the force and the time

• the mass and the force

• the radius and the area

• the displacement and acceleration

from the examples of vector physical quantities is............

• displacement

• mass

• time

• distance

the shortest distance covered by the object in a certain direction is called ..................

• distance

• displacement

• acceleration

• speed

the distance and displacement are equal when the body moves in a...................

• curved path in one direction

• curved path in opposite direction

• straight line path in one direction

• straight line path in opposite direction

when an object complete one circular bath of diameter 10 meters, its displacement is..................

• 10 m

• 5 m

• 2.5 m

• zero

a body moved a distance of 20 m in a straight line in the same direction, so, the amount of its displacement is...........

• 20 m

• 40 m

• 80 m

• zero

if a person moves 8 m to the north, then 4 m to the east, then 8 m to the south, his displacement equals.................. in the east direction

• 20 m

• 4 m

• 8 m

• 12 m

the average velocity is determined by the relation ..................

• distance / time

• distance X time

• displacement / time

• speed / time

the plane which flies against the wind direction ....................than that which flies in the same direction of wind.

• consumes more fuel

• takes a shorter time

• its speed increases

• consumes less fuel
