Assuming the stone is raised at a constant velocity (no acceleration) note that ##\vec F_{net} = \vec W## + ##\vec B## + ##\vec L## = 0 Or in terms of magnitudes ##F_{net} = -W + B + L = 0## Mar 9, 2022 #67 rudransh verma Gold Member 1,067 ...
What is the difference between constant velocity and acceleration? A ball is dropped from the top of a tall building of height H. It falls from rest, accelerating uniformly until it strikes the ground below. How does the time it takes to fal...
Use the gravitational acceleration found on Earth: g = 9.8 What is the force of gravity due to the Moon on a 52.0 kg student standing on the equator during spring break? G = 6.67 x 10-11 m3/kg/s2; mean distance to the Moon = 3.84 x 108 meters;...
The velocity profile, illustrated in the right panels of Fig. 6 as a speed variation profile, showed homogeneous average profiles but large standard deviations in sequence A. Standard deviations and mean profiles in sequence B varied less between groups, reflecting a more homogeneous participant ...
So why does gravity pull you down and not push you away? Imagine someone went under the trampoline and pushed up. The ball would roll away! This would be a gravity hill, not a gravity well. As far as scientists know, matter – or stuff – always makes gravity wells and not gravity ...
The second derivative isthe rate of change of the rate of change of a point at a graph(the "slope of the slope" if you will). This can be used to find the acceleration of an object (velocity is given by first derivative).

(A) A Kruskal-Wallis test determined that there was no statistical significance between the mean pixel intensities of the experimental and negative control groups (p = 0.6605). The mean pixel intensity of the positive control group was determined to be significantly higher than that of ...
Is that acceleration given by spacetime curvature difference from “point to point”? E.g as it’s increasing “downwards” it makes it look like the ball needs less and less time to cross the same space distance? But this would mean that any object would need to pick up “starting” do...
How does force, time, displacement, and velocity affect power? What does 'vector quantity' in forces mean? What force is the underlying cause of contact forces? Why is the weak force an intrinsically short range force? How is net force calculated? How can you cause charge to build up on...
