Answer the following question given this paragraph: Gyroscopes used in guidance systems to indicate directions in space must have an angular momentum that does not change in direction. Yet they are often subjected to large forces and accelerations. How can the direction of their angular momentum be constant when they are accelerated?. Q: What instruments used in guidance systems to indicate directions in space must have an angular momentum that does not change in direction? Choices: - actuators - elevators - magnets - gyroscopes A:
(Answer)
gyroscopes
Ques: Answer the following question given this paragraph: Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction. This explains why most forms of ground transportation use wheels, including bicycles, cars, 4-wheelers, roller skates, scooters, and skateboards. Ball bearings are another use of rolling friction. You can see what they look like in the Figure below . They let parts of a wheel or other machine roll rather than slide over on another. Q: What is friction that acts on objects while it is rolling over a surface called? Choices: - blowing friction - opposing friction - surface friction - rolling friction A:
Ans: rolling friction
