What is the net force on a car moving in a straight line which a constant speed?
The net force on a car moving at a constant speed in a straight line is zero. This is because the forces acting on the car, such as friction and air resistance, are balanced by the force produced by the engine to maintain the constant speed.
Can all forces of a car be balanced if it is moving a constant velocity?
Yes, if a car is moving at a constant velocity, all the forces acting on it are balanced. The forward force of the engine and the opposing forces such as air resistance and friction are all equal, resulting in a net force of zero and the car moving at a constant speed.
Infer whether balanced forces must be acting on a car moving at a constant speed?
Yes, if a car is moving at a constant speed, balanced forces must be acting on it. This means that the force pushing the car forward is equal to the resistive forces acting against it (like friction and air resistance), resulting in zero net force and a constant velocity.
Is a car balanced or unbalanced when turninng while moving at a constant speed?
The forces acting on the car are unbalanced because it is accelerating by changing direction, even though it has constant speed. Unbalanced forces cause acceleration (change in motion). That is what Newton's first law of motion is about.
If a car moves at constant speed also moving at constant velocity give an example?
An example of a car moving at constant speed and constant velocity would be a car driving along a straight road with no change in direction, where the speedometer shows a steady reading, and there are no changes in velocity or direction of motion. This means the car is moving at a consistent speed in a straight line without any acceleration or deceleration.

Can balanced forces act on a moving objects?
Sure. If all of the forces on an object are balanced, then the object continues moving in a straight line at constant speed. All of the forces on an airplane cruising in level flight, or on a car on cruise-control on a straight piece of road, are balanced.
Can balanced forces act on moving object?
Sure. If all of the forces on an object are balanced, then the object continues moving in a straight line at constant speed. All of the forces on an airplane cruising in level flight, or on a car on cruise-control on a straight piece of road, are balanced.
When does a car move at a constant speed?
A car moves at a constant speed when the acceleration is zero. This means that neither the speed nor the direction of the car is changing. Once all external forces are balanced and there is no net force acting on the car, it will continue to move at a constant speed.
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.
Does a car accelerate rounding a curve at a constant speed?
No, a car does not accelerate when rounding a curve at a constant speed. Acceleration occurs when there is a change in speed or direction. In this case, the car is moving at a constant speed but is changing direction, not accelerating.
What is the net force on a car stopped at a stop sign what is the net force on a car moving in a straight line with a constant speed?
When a car is stopped at a stop sign, the net force on the car is zero because no motion is occurring. When a car is moving in a straight line with constant speed, the net force on the car is also zero because the forces acting on the car (like air resistance and friction) are balanced by the force generated by the car's engine.
What is the acceleration of a car moving at a speed of 50mph?
If the speed is constant at 50 mph, then the acceleration is 0.
