Albert Einstein theory of general relativity
tug of Gravity
A marble rolled around the edge would spiral inward toward the body, pulled in much the same way that the gravity of a planet pulls at rocks in space
trampoline The body would press down into the fabric, causing it to dimple.
massive objects caused a distortion in space-time.
Sir Isaac Newton quantified the gravity between two objects when he formulated his three laws of motion
The force tugging between two bodies depends on how massive each one is and how far apart the two lie
which describes gravity not as a force, but as a consequence of the curvature of space time caused by the uneven distribution of mass.
Space and time
Velocity, or speed, of light
a system of one temporal and three spatial coordinates by which any physical object or event can be located.
defined time in a specific way by saying it is what we measure with clocks
space-time continuum. 2 : the whole or a portion of physical reality determinable by a usually four-dimensional coordinate system also
physics, space time is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum.
gravity can bend time. Picture a four-dimensional fabric called space-time. When anything that has mass sits on that piece of fabric, it causes a dimple or a bending of space-time.
Show that one motion has two speeds, one space sets of dimensions, and one event seems to occur at different times
Einstein explained that an event can be identified by three spatial dimensions---Length, width, and height-- and by the time the event occurred
measurements change for motion and speed
he laws of physics which apply when you are at rest on the earth also apply when you are in any reference frame which is moving at a constant velocity with respect to the earth.
toss and catch a ball in a moving bus if the motion is in a straight line at constant speed.
