Given that we are talking about a theory of physics, the Lorentzian arc length is the one that has physical meaning in the theory; the Euclidean arc length does not. So using the term "arc length" for the Euclidean one in the context of the physical theory is at least as confusing as...
How far away does the cannonball land? Calculate the impact speed (ignoring air resistance) of an object dropped from a specific height or the maximum height reached by an object (ignoring air resistance), given the initial verti...
This is different from the pressure a fluid will exert on you if you get in the way of it and stop its motion. [I still don't get the difference.] Note that Bernoulli's principle does not say that a fast moving fluid can't have significantly high pressures. It just says that ...
Gravity is the force exerted by objects that possess mass on other objects that possess mass (as far as classical physics and daily life are concerned). Its strength depends on the separation between the objects. The overall equation for the force of gravity is: ...
Also, the final ball rises to a level equal to the dropping height of the first one, signifying that all energy is also saved! Final Words Although the working procedure and physics behind the cradle are quite straightforward, individuals often inquire: What if we dropped two balls instead of...
W = m×g×h = mgh Above is the potential energy formula. As per thelaw of conservation of energy, since the work done on the object is equal to m×g×h, the energy gained by the object = m×g×h, which in this case is the potential energy E. ...
Find an expression for the work the elevator cable does on the elevator.An elevator of mass m rises a vertical distance h with an upward acceleration equal to one-tenth g. Find an expression for the work the elevator cable does on the elevator....
An object falls from rest at a great height. Neglecting air resistance, what distance has it fallen in the first 2.0 seconds? A stone is thrown vertically upward with a speed of 14. m/s from the edge of a cliff 75m high. ...
