What happens to the speed of an object when the net force acting on an object is zero?

An object’s velocity (a vector) does not change if and only if the net force acting on the object is zero. In other words, if there is no net force on an object, its speed and direction of motion do not change (including if it is at rest).

What is the net force of an object moving at a constant speed?

Answer: 0 N If the velocity is constant, then the acceleration is 0 m/s/s and the net force is zero. A net force is only required in order to accelerate an object.

What would be the net force on an object if the object’s acceleration is 0?

If there is zero acceleration, that means there is no net force on the object, or .

Does an object that is not accelerating or decelerating has zero net force acting on it?

An object that is not accelerating or decelerating has zero net force acting on it. The only way to slow down a moving object is to apply a net force to it. When no net force is applied to a moving object, it still comes to rest because of its inertia.

Is the net force acting on a moving object on a smooth surface becomes zero then?

there is no net force acting on the object. the object moves with constant velocity.

What is the net force acting on an object which is acted upon by a number of balanced forces?

The direction will be the opposite direction in the balanced force. The object stays at rest in the balanced force. The speed of the object continues to move in the same speed. And the net force acting will be zero.

What must be true about the net force if an object is to move at a constant speed in a straight line?

be zero because an object moving in a straight line at constant speed has zero acceleration because the net force acting on it is also zero. The forces are equal in size, act in opposite directions, and produce a zero net force. This is because the car is subject to two forces acting along the direction of motion.
