Expert Answer:

Hi dear,

For any object moving with the same speed, net force is zero.

According to newton's laws of motion,

F = dp / dt, p is the momentum of the system, and F is the net force. In equilibrium , there is zer net force , but ( balanced forces) may be present. Again, if an unbalanced force acts upon the system, there is a change in momentum of the object.

Hope this satisfies your requirements.

Regards,

Aruna
