Why forces acting on a car as it moves along a level highway in still air at a constant speed?
The main forces acting on a car moving at a constant speed on a level highway in still air are the driving force from the engine propelling the car forward and the opposing forces such as friction between the tires and the road and air resistance. When these forces are balanced, the car will continue to move at a constant speed.

Why are forces balanced when traveling at a constant speed?
If there be net force then it has to be accelerated. So the magnitude of the speed cannot remain the same. But in case of a body moving with a constant speed along the circular path, the forces will be centripetal and centrifugal both acting in opposite direction. So the body would not have displacement along the radial path.
Does a car traveling along a curved path at constant speed have a constant momentum?
Yes, a car traveling along a curved path at constant speed does not have constant velocity since velocity is a vector quantity that includes direction. However, the magnitude of the car's momentum (which is the product of mass and velocity) can remain constant if there are no external forces acting on it.
A bicycle is being ridden along a horizontal road by a pedal force of 400 N Its speed is constant at twelve ms What is the total value of the frictional forces acting on the bike and its rider?
The total value of the frictional forces acting on the bike and its rider would be 400 N, which is equal in magnitude to the pedal force applied. This is necessary to balance the pedal force and maintain a constant speed when the bicycle is moving at a constant velocity.
What is a situation in which balanced forces are acting on a bike?
When the bike is not moving, there is an equal force between the bike and a surface. If you are seated on the bike in a still position, you and the bike would create an even balanced force. If you accelerated, you would create an unbalanced force.
When two forces P and Q acting along the same line then its resultant?
The resultant of two forces P and Q acting along the same line is the algebraic sum of the two forces. If they are acting in the same direction, the resultant is equal to the sum of the forces. If they are acting in opposite directions, the resultant is equal to the difference between the two forces.

A race car travels along a raceway at a constant velocity of 200 kmh what horizontal forces act and what is the net force acting on the car?
Drag forces are trying to slow the car down. Engine power to the wheels generates force that equals the drag, and keeps the car travelling at a constant speed. The sum of all forces on the car are zero, which is why it is not accelerating or decelerating.
When two forces P and Q acting along the same line then its resultant?
The resultant of two forces P and Q acting along the same line is the algebraic sum of the two forces. If they are acting in the same direction, the resultant is equal to the sum of the forces.

If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
What do it means when they say balanced forces?
When forces are balanced, the total force acting on an object is zero, resulting in no change in the object's motion. This means that the forces acting in opposite directions cancel each other out. As a result, the object either remains at rest or continues to move at a constant velocity.
Does an object at rest have forces acting on it and if so what forces would be along the vertical axis?
Yes, an object at rest can have forces acting on it. The vertical forces acting on an object at rest would include gravity pulling it downward and the normal force from a surface pushing it upward to balance the force of gravity.
What is the relationship between rolled distance and time taken?
If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.If an object is rolling along a plane horizontal surface with no other forces acting on it, then rolled distance is directly proportional to the time taken.
When a car moves along the highway at constant velocity the net force is zero why then do you continue to run your engine?
The key point is that the net force is zero. This is not the same as having zero force acting on it. The forces of drag and friction are always acting on moving objects, and the engine generates a force through the wheels that balances out this force, keeping you at a constant velocity. If the engine was stopped, this counterforce would no longer be in effect, and the unbalanced force of the drag would eventually slow the car to a stop.
What are the forces acting on an cyclist which is slowing down?
As the cyclist increases its speed, so too does the frictional force. The cyclist will keep accelerating until both the forces become balanced. The cyclist will then remain at a constant speed until one of the forces changes again. Hope this helps
