Using a stopping distance of 3 cm and a terminal velocity of 20 m/s gives an acceleration of 6666 m/ 2 or 680 g’s. If I use a terminal velocity of 12.2 m/s, the stopping acceleration goes down ...

The diagram shows a velocity-time graph for an object falling through a fluid, eg air, water, oil. Between A and B The object accelerates at first because of the force of gravity.

Note that acceleration is a vector and so is the velocity. In short, a vector has both magnitude and direction (here is the long version of vectors).Now I am going to draw a diagram for a person ...

At t 2, the angular velocity is zero, with a non-zero (positive) angular acceleration. At that time, the direction of rotation for BC is changing from CW to CCW. In summary, you should never assume ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 ...
