Physics Blog 5: Picture Poses

This past week was Homecoming, and there were probably hundreds of possible topics for blogs. However, I really noticed physics at work when we were taking a group picture:

You can see on the right hand side that my friends Val and Andrew and I were holding Kevin motionless in the air. To achieve this, we had to offset his weight with the force we were applying from beneath him, and since he was not touching the ground, our three forces combined had to equal what the normal force would have been. If you look at other people in the picture, you can see other examples of the normal force being replaced with an equal force. PHYSICS IS FUN!! :)
