Question 1 When you jump up in the air and become a projectile, can you control where your center of gravity is relative to the ground while you’re in the air? (2 pts) No. Nobody can control where their center of gravity is relative to the ground when they're in the air. Why or why not (1pt) Once in the air, the body is technically a projectile. The only external force acting on a person is gravity, so the center of gravity changes due to the acceleration of gravity but we can’t change it. Moving your arms and legs does not change your center of gravity because they are not pushing or pulling anything external to your body. The class book identifies 3 factors that influence stability. During the balance/stability exercises for this week, which of those 3 was the limiting factor that caused instability? Explain. (2 pts) The 3 factors that influence stability are the height of the center of gravity, the size of the base of support, and the weight of the object. In the exercises this week, we had to stand on our toes or lift one foot off the ground. This made our center of mass

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
