Are there forces acting on a car that is at rest xy?
There are forces acting on the car. They are just equal to the force of the car acting on the force. In example, gravity is acting on the car, but the car is pushing back equally. Therefore, the car doesn't move.
Infer whether balanced forces must be acting on a car moving at a constant speed?
The friction force acting upon the turned wheels of the car cause an unbalanced force upon the car and a subsequent acceleration.
You are sitting in a car driving at a constant speed on a flat road What are all of the forces acting on you not the forces acting on the car?
Moving at a constant speed if your in the car then there are no forces acting on you from the car. If the car accelerates then the car will push you forward and you will feel the Force of the seat pushing you. The only other force on you in a car is gravity witch always pulls straight down. Gravity is always there whether the car is accelerating or not.
What forces are acting on a moving car?
Friction
What forces are acting on a still car and a car that is slowing down?
There are more than two forces acting on a moving car. The force of gravity keeps the car on the ground, and the normal force from the ground keeps the car from falling to the center of the earth. When the engine is running, it creates a torque which is transferred to the car's tires. Due to small and large cracks and crevices in the road and tires the two surfaces keep getting stuck together. The force must go somewhere, so the car is now applying a force on the road in the direction the wheels are rotating. Newton's 3rd law states that, "For every action, there is an equal and opposite reaction," therefore the road also applies a force to the car. This force is called a frictional force. It is static friction if the car is moving, and the tires are not sliding; it is kinetic friction if the car is moving, but the tires are sliding. This frictional force is what propels the car and is greater as static friction. The last force acting on a moving car is the drag force or air resistance and it is caused by particles of air running into the car, slowing it down.

What do you say if you're in the mood to correct the mistaken statement of a friend xy?

What is meant by all forces in pairs?
When a force is acting on an object, there is always another equal and opposite force acting upon it. For example; a car that is travelling forward has a force of 'Thrust' which is pulling the car forward, as this occurs, 'Drag' or 'Air resistance' is also acting upon the car.
Is it possible for a car moving with a constant velocity to have forces acting on it?
No,because if the car is moving at a constant velocity that means the acceleration is zero. So the net force is zero and there may be some forces acting on it. Only gravity, downward.

What is a practical example of gravity acting on a moving object?
A car speeds up as a traffic light turns green.
What forces are acting on a moving car?
Friction
Why do moving body accelerate?
Not all moving objects accelerate. In general, an object will accelerate if there is a net force acting on it. For a ball in the air, this might be gravitation + air resistance; for a moving car (once you turn the engine off) it might be the force of friction; etc.

Cases when there is displacement but no force is applied?
When an object gets displaced in the absence of force acting on it, it must have already been moving? In the past a force acted on it and now the force is no longer acting on it. Like pushing on a toy car and letting go. The car continues to roll after you let go.
What force is acting on a body moving with uniform speed on a perfectly smooth road?
1) There are always frictional forces, which by themselves would slow the car down. 2) Since we are assuming that the car is moving at a uniform speed, there must be another force to compensate for the friction, and in the opposite direction (pulling the car forward). This force is related to the effort done by the engine.
