What else can I help you with?
If we are told that an object has a constant velocity what can we say about the force on that object?
If an object is moving with constant velocity, then the net force acting on it is zero. This means that the forces acting on the object are balanced, resulting in no acceleration and a constant velocity.
When the net force on an object is zero we say that the two forces are?
When the net force on an object is zero, the two forces acting on the object are balanced or equal in magnitude but opposite in direction. This is known as equilibrium.
What is the velocity of an object if the net force on the object is zero?
You can't tell. The only thing you can say is that as long as the net force onan object is zero, the velocity is constant. We don't know what that velocityis, but it doesn't matter. Whatever it is, it remains constant. Contrary to oureveryday experience on Earth, no force is required to keep something moving.By the way, that also means that the object's acceleration is zero when thenet force on it is zero.
If you add together all of the forces exerted on an object and get a non-zero value this is called?
This is called a net force. The net force is the combined effect of all forces acting on an object, and it determines the object's acceleration according to Newton's second law of motion.
What is a non zero net force mean?
That means that the sum of all the forces on an object, that is to say the vector sum, results in a force that is not zero. The forces are not balanced. In this case, the object will accelerate (its velocity will change).
What is a non non zero net force?
That means that the sum of all the forces on an object, that is to say the vector sum, results in a force that is not zero. The forces are not balanced. In this case, the object will accelerate (its velocity will change).
What type of force does an object have if its net force is equal to zero?
If the net force on an object is zero, we can say that the forces are balanced, or that they are in equilibrium(which really means the same thing). There may be forces acting on the object, but there is an equal and opposite force pushing or pulling in the opposite direction, and all the forces balance out. Alternatively, there may be no forces acting on the object at all.
If an object is moving at a constant speed what do we know about the forces acting on the object?
Not much, really. If the object's direction is changing, then the velocity changes, and there are forces acting on it. The only thing we can say is that the net force acting on the object is either zero, or it is perpendicular to the movement.If the VELOCITY doesn't change, then the net force (the sum of the forces) is zero.
Is an object is stable what we can say about this object's force?
If an object is in static equilibrium (or "stable"), there is no net force acting on the object.
What happens to an object when a force acts on it over time?
If there is no counter-force (such as friction), in other words, if there is a NON-ZERO NET FORCE, the object will accelerate. That is to say, its velocity will change.
What happens to a moving object with zero nets force acting on it?
Certainly. Say you have an object that has been falling through the air for a long time, say a skydiver. After falling for a long time, the skydiver will fall at a constant velocity. This is called terminal velocity, and this is when the air resistance pushing up around the skydiver is equal to the force of gravity pulling the skydiver down. The skydiver is not accelerating. By using F= ma, with zero acceleration, there is zero net force. The skydiver is moving as if there are no forces acting on the skydiver.
What can we say about the forces on an object that is not moving?
If an object is not moving, the forces acting on it must be balanced. This means that the net force on the object is zero, resulting in no acceleration and maintaining a constant velocity or state of rest.
