Question

A CAR MOVING WITH UNIFORM VELOCITY. WHAT IS THE NET FORCE ACTING ON IT ? WHAT CAN YOU SAY ABOUT THE FORCES ACTING ON IT?

Answer 1

When an object moves with constant velocity the resultant force acting on the body is zero.You don't need a force to keep something moving.  You just need a force to get it moving.  Or to STOP it moving.  In your day-to-day experiences, anything you get moving seems to come to a stop after you stop pushing it.  That's because there are forces (friction) that cause it to stop.  Without those forces, the object would just keep moving along. 

i hope it will help you

Answer 2

I think constant force is working on it Thats why it moves with constant velocity . but no external force is applied on it and it will follow inertia of motion
