1. How to Draw a Force Diagram to Find the Net Force Acting on an Object<br />
2. First, identify the object (or the system of objects) which you wish to study.<br />In this example, our system will be Ms. Clanton standing still in the physical science classroom<br />
3. Next, draw a rectangle or a circle to represent the object (or system of objects) which you are studying.<br />Draw a dashed circle around the object you are studying; the dashed circle represents the system you are studying. Only the object (or system) you are studying is in the dashed circle; everything else is outside.<br />

5. Then, draw everything which touches the object (or system of objects) which you are studying.<br />
6. Next, identify any forces which are acting on the object you are studying.<br />At least one contact force acts at each point where the object you are studying is touched.<br />Identify any forces which act at a distance (gravity, for instance). <br />

8. Next, identify any forces which are acting on the object you are studying.<br />At least one contact force acts at each point where the object you are studying is touched.<br />Identify any forces which act at a distance (gravity, for instance). <br />Contact Force: Support Force<br />

Next, identify any forces which are acting on the object you are studying.<br />At least one contact force acts at each point where the object you are studying is touched.<br />Identify any forces which act at a distance (gravity, for instance). <br />Support Force<br />Contact Force: Support Force<br />
10. Next, identify any forces which are acting on the object you are studying.<br />At least one contact force acts at each point where the object you are studying is touched.<br />Identify any forces which act at a distance (gravity, for instance). <br />Support Force<br />
11. Next, identify any forces which are acting on the object you are studying.<br />At least one contact force acts at each point where the object you are studying is touched.<br />Identify any forces which act at a distance (gravity, for instance). <br />Gravity always pulls down on an object if the object is at or near the surface of the earth.<br />Support Force<br />

13. Finally, you can find the net force acting on the object you are studying by adding up all of the force vectors in the diagram.<br />For this example, the force vectors are equal in size but opposite in direction. So, they cancel out.<br />The net force acting on the object we are studying is zero.<br />Support Force<br />Force of Gravity<br />
