... Driving a car through a bend Is there a force that pushes you away from the center of the circle? • Newton’s first law: If no net force is acting on an object, it will continue with the same velocity (inertia of mass) • Velocity is a vector (points to a direction) • If no net force is acting on an ...

The Coriolis effect is a deflection of moving objects when
... Newton's laws of motion govern the motion of an object in a (non-accelerating) inertial frame of reference. When Newton's laws are transformed to a uniformly rotating frame of reference, the Coriolis and centrifugal forces appear. Both forces are proportional to the mass of the object. The Coriolis ...

... Although the conservation of energy and momentum gives us some information about the collision, it is not enough to uniquely determine the final outcome. It’s easy to see why: we have six unknowns in the two velocities v1 and v2 , but just four equations in (5.4) and (5.5). Acting on Impulse When pa ...

Precession
Precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. In other words, the axis of rotation of a precessing body itself rotates around another axis. A motion in which the second Euler angle changes is called nutation. In physics, there are two types of precession: torque-free and torque-induced.In astronomy, ""precession"" refers to any of several slow changes in an astronomical body's rotational or orbital parameters, and especially to Earth's precession of the equinoxes.
