... • Consider the gymnast hanging from the rings. If she hangs with her weight evenly divided between the two rings, how would scale readings in both support ropes compare with her weight? • The reading on each scale will be half her weight. The sum of the readings on both scales then equals her weight ...

Chapter 5 Work and Energy conclusion
... Collisions involve two new concepts: Impulse and Momentum. Impulse concept leads to the Momentum definition. Also applied to two (or more) masses blown apart by an explosion. ...

Equations of Motion - School of Engineering
... Even though the equation has been simplified by excluding Frictional effects and combining the Centrifugal force with the Gravitational force, it is still a complicated equation. To further simplify, a process known as Scale analysis is employed. We simply assign typical scale values to each element ...

... The momentum of an object doesn’t change unless its mass, velocity, or both change. Momentum, however, can be transferred from one object to another. The law of conservation of momentum states that if a group of objects exerts forces only on each other, their total momentum doesn’t change. ...

... 1.7 N. 31. Picture the Problem: The free-body diagram for the contact point between the two strings is depicted at right. Strategy: The horizontal components of the string tensions must be equal because the picture is not accelerating. The same is true of the vertical components of the forces. Use N ...

... 8. In 1976, Gerard O’Neill proposed that large space stations be built for human habitation in orbit around Earth and the moon. Because prolonged free-fall has adverse medical effects, he proposed making the stations in the form of long cylinders and spinning them around the cylinder axis to provid ...
