Motion quiz -1

Which type of speed does the speedometer of a car measures?

• Average speed

• Instantaneous speed

• Uniform speed

• Increasing speed

Which of the following is most likely not a case of uniform circular motion?

• (a) Motion of the earth around the sun

• (b) Motion of a toy train on a circular track

• (c) Motion of a racing car on a circular track

• (d) Motion of hours’ hand on the dial of a clock

How is displacement different from distance?

• displacement is a vector, it must have magnitude and direction

• displacement is a vector, it must have magnitude only

• displacement is a scalar, it must have magnitude and direction

• displacement is a scalar, it must have magnitude only

Acceleration: is the rate of change in ___________.

• speed

• distance

• velocity

• displacement

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

Displacement can be:

• Zero

• more than distance

• equal to distance

• negative

Displacement shows magnitude while distance shows both magnitude and direction

• TRUE

• FALSE

choose the correct formulas:

(related to speed)

• speed = distance/time

• time = distance/speed

• average speed = total distance/total time

• distance = speed*time

• speed = displacement/time

Acceleration is:

• everything

• scalar quantity

• vector quantity

• nothing
