Is it true or wrong to say that an object with zero acceleration has velocity? Either yes or no explicate it with example.


Ans: . The velocity and acceleration of a particle do not depend on each other (however rate of  change  of  velocity  with  respect  to  time  gives  acceleration  )  i.e  if  velocity  is  zero acceleration  may or may not be zero or vice versa.
Example :
Consider  a  simple  example  when  we  start  a  vehicle,  initially  we  have  zero  velocity  but have non-zero acceleration(that is why vehicle will start moving).
2.If we drop a ball from some height above the earth surface the velocity at that instant is zero but acceleration in non zero (gravity) which acts downward. The acceleration would increase the velocity in some time.


Can  we  say  that  an  object  with  zero  velocity  have  acceleration?
Either  yes  or  no explicate it with example.


Ans:  Yes, an object can have zero velocity and still be accelerating simultaneously.
Example:
Consider an object moving in the forward direction. suddenly a force actson it and tries to acceleration the object in the backward direction . when you observe the object, you will find  that  the  object  will  continue  to  move  forward  for  some  time  and  then  stops momentarily. Then the object will start to move in the backward direction.


Is  it  wrong  or  correct  to  say  that,  if  an  object  has  constant  acceleration,  it  has  a constant velocity? Either yes or no explicate it with example.


Ans: An  object  with  a  constant acceleration should  not  be  confused  with  an  object  with  a constant velocity.
If an object is changing its velocity whether by a constant amount or a varying amount then it is an acceleration object. And an object with a constant velocity is not accelerating.

Q.2     Estimate the soccer ball‘s speed immediately after being kicked off if its mass is
0.5Kg
Ans:
F=256N
Distance =0.2M
Mass =0.5KG
Velocity=?
FORMULA:F=ma
As we know acceleration is equal to a =∆𝒗/∆𝒕
F=m(=∆𝒗/∆𝒕)
256=0.5(velocity time)
Velocity = 256 / 0.5×time
Velocity = 256 / 0.5×1
Velocity = 512km/s
