    B Is Gravity Really a Force? A Look at General Relativity's Perspective

    relative to another object in space which moves at same speed at the beginning, accelerating through Earth with 9.81m/s^2 is a force because both will not have same speed at the end. Space ships use gravity for sling shot so they increase speed with it thus it should be force

    How to calculate compression of a spring

    inertia moment of long uniform rod through end is I=1/3ML² what if rod has hollow. what is inertia moment?

    How to calculate compression of a spring

    centrifugal force apply force to spring while it spinning, how to calculate it's compression. there is no any attached mass on spring. just centrifugal force depends on RPM. weight of spring is important, centrifugal force is changing by radius, so it's not uniform.

    Why light can't penetrate the prism with 45 degree angle

    Light can penetrate with 0 degree of normal of surface and it is reflected with 45 degree of normal of surface. as it seems in illustration. Density of glass is more than air. I don't ask a specific question about that. my point what is the reason of reflection of light depends on angle of it

    Why is gravitational acceleration independent of test masses?

    curvature depends on height of object from ground thus parabolic curvature change for any height.?

    Why light can't penetrate the prism with 45 degree angle

    it's not a unique question in fact. it's a general question about the situation of light can't penetrate prism and reflect back. one reason is difference of density...

    Why light can't penetrate the prism with 45 degree angle

    Let say, light comes with wide angle like 60 degree of normal of surface and reflect with same angle. there is a formula about that in the web page. why it can't penetrate the prism with wide angle? difference of density between prism and air is a factor, is there another reason for it

    Why is gravitational acceleration independent of test masses?

    height=1/2gt2= 4.9m 1st sec. 19.62m 2nd sec. 44.14m 3rd sec. 78.48m 4th sec. bending space time parabolic is only way to provide motion to object at constant velocity, flow of time doesn't accelerate or decelerate via bending...

    Why is gravitational acceleration independent of test masses?

    yes. I checked the web site. The formula F=ma is a Newton's second law which is same formula with gravity. F=m g, gravitational force is 9.81m/s2 equal for all objects in world. thus proportion of F1/m1=F2/m2=F3/m3=F4/m4...= gravity. Mass of gravitational = Mass of inertial for any object . a...

    Why is gravitational acceleration independent of test masses?

    F1/m1=F2/m2=F3/m3.....= gravity. formulas don't explain the reason why all object fall at same time.

    Why is gravitational acceleration independent of test masses?

    i need to fix my last sentence, it would be if there is no force, no acceleration which is gravity. Newton's first law says, if an object is moving along, untouched by a force of any kind, it will continue to move along in a perfectly straight line at a constant speed...

    Why is gravitational acceleration independent of test masses?

    if gravity isn't a force, how objects act the same way,... moving through curved space time? if there is no force, no motion
