When a particle moves with constant velocity, its average velocity, it instantaneous velocity and its speed are all equal. Comment on this statement.
When
a particle is moving with constant velocity then its magnitude and direction
both are not changing means particle must travel in straight line. Also when
particle is moving in straight line with no acceleration then distance covered
and displacement both will be same in same interval of time. Hence average
velocity and average speed both will be sameas average velocity =( net
displacement)/time And average speed= (total distance)/time.Instantaneous
velocity will be same as velocity is not changing anywhere.Hence according to
me this statement is very true.
If
velocity is always constant then it will be the same at every instant ie
instantaneous velocity is same and also if it is constant then there is no
question of average velocity changing. Also if velocity is constant its modulus
or speed is also constant.
