An object with Fnet = 0 moving at a constant velocity. FBD Diagram
I don't understand how this is possible, if some one could please explain it to me and if possible draw a quick diagram on an external site. (i.e. Sumopaint )
If there is no net force, there is no net acceleration and velocity is constant.
Force = rate of change of momentum
F = m A
if m is constant
You're confusing acceleration and velocity. Acceleration is a CHANGE in velocity.
Sure! Let me explain it to you step by step.
First, let's talk about the situation you mentioned: an object with a net force (Fnet) of 0 moving at a constant velocity. This situation occurs when the object is not experiencing any external forces that could change its state of motion.
To understand how this is possible, we need to look at Newton's first law of motion, also known as the law of inertia. Newton's first law states that an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity in a straight line, unless acted upon by an external force.
In the case you described, the object is already in motion and continues to move at a constant velocity. This means that the object is experiencing an equal and opposite force that cancels out any external forces acting on it.
Now, let's create a free body diagram (FBD) to visualize this situation.
1. Draw a dot or a simple shape to represent the object in the center of the diagram.
2. Label the dot or shape as your object.
3. Draw arrows representing all the forces acting on the object. In this case, since the net force is zero, there should be no arrows pointing outward from the object or any forces acting upon it.
4. Make sure to include labels for each force you draw. However, since there are no external forces, the labels can be left blank or simply write "0" to represent the zero net force.
Remember, the purpose of an FBD is to help us understand the forces acting on an object in a given situation. In this case, with Fnet = 0, the FBD will show no external forces acting on the object.
As for drawing the FBD on an external site like Sumopaint, you can follow these steps:
1. Open an online drawing tool like Sumopaint.
2. Create a new canvas and choose the size that suits your needs.
3. Use the tools provided in the drawing tool to draw the dot or shape representing the object.
4. Use the drawing tools to add arrows to represent the forces acting on the object. In this case, you do not need to draw any arrows since the net force is zero.
5. Add labels to the forces if you wish. Since there are no external forces, the labels can be left blank or simply write "0" to represent the zero net force.
6. Save the diagram and share it as needed.
I hope this explanation helps you understand how an object can have a net force of 0 and still move at a constant velocity! Let me know if you have any more questions.
