Motion and Time

The distance moved by an object in a unit time is called

• acceleration

• speed

• motion

• displacement

the S.I unit of speed is

• cm/s

• cm

• m

• m/s

Speed =

• distance covered

• distance covered X time taken

• distance covered / time taken

• time taken / distance covered

Motion which repeats itself in a regular intervals of time is called ..............

• Linear motion

• circular motion

• periodic motion

• irregular motion

Motion of objects can be presented in pictorial form by their...............
