10-1 Note 10 Rotational Motion I
... To find the direction of the ω vector, extend your right hand, curl your fingers as if you are to grip something and extend your thumb. Now curl your fingers in the direction of the angular displacement of the object (the direction the object is rotating). Then your thumb points in the direction of ...

QUICK QUIZZES 1. Newton`s second law says that the acceleration
... The mass of an object is the same at all locations in space (e.g., on Earth, the Moon, or space station). However, the gravitational force the object experiences weight, w mg does vary, depending on the acceleration of gravity g at the object’s current location in space. It is the gravitation ...

By choosing a reference frame with the initial condition x0 = 0m, one can easily find the displacement of the rock in three second. From the initial location, the rock would fall 16.7 m in three second. The anal ...

... Chapter 7 is about the COLLISION of two masses. Both masses are needed to understand their interaction. Newton's 3rd Law plays a very important part. Collisions involve two new concepts: Impulse and Momentum. Impulse concept leads to the Momentum definition. Also applied to two (or more) masses blow ...
