It is seen that the contact force F is directly dependent on the Coriolis component of acceleration. Note that the sign on F changes as the sign on x_dot changes; that is, when the particle is moving ...

The object is still accelerating but its acceleration decreases as time goes by. Its speed still increases but by a smaller amount. The resultant force still acts downwards but is decreasing.

He used a thought experiment to compare the force felt from gravity with acceleration. Imagine you are in an elevator and feel what you believe is the force of gravity, holding you to the floor.

unseen force thought to permeate space and drive this acceleration. The Pantheon+ dataset is the most extensive and precise collection of type Ia supernovae ever assembled. Spanning decades of ...
