displacement of the car?
5. A car is moving at the rate of 40 km/h towards east. Which physical quantity is stated here,speed or velocity?​

Answer 1

Answer:

1.The motion in which every point on the moving body moves through the same distance in the same interval of time is called Translatory motion

2.Oscillatory motion is defined as the to and fro motion of an object from its mean position. The ideal condition is that the object can be in oscillatory motion

3.Vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude
