Lower Back.Gravity pulls the bar down when you Squat. Your lower back must resist this downward force to keep your spine neutral and safe. This strengthens the muscles on the back of your spine which protects it against injury. Abs.Your ab muscles help your lower back muscles to keep your...
The speed oflightisn’t affected by gravity. The curvature of space-time causes it to bend, but the actual speed oflightis unchanged. However, iflighttravels through a material, such as a glass plate, it will slow down. This is because the particles in the medium will scatter thelight, ...
Einstein's General Theory of Relativity predicted that gravity could bend space. This was later confirmed during a solar eclipse when a star's position was measured before, during and after the eclipse. The star's position shifted because the light from the star was bent by the sun's gravity...

Some suppose that the special gravity(重力 ) in this area has caused the trees to bend northwards.But it seems that this guess isn't proper,because gravity only pulls things downwards and doesn't make them bend.Others guess that the heavy snowfall in the area weighed do...

When your pinwheel helicopter falls, it is due to the force of the earth’s gravity. Lift, and the design of the rotors help it stay in the air. It naturally falls to the ground, which causes the paper to bend slightly upward due to lift. When your paper helicopter falls, air pushe...
Intake - Gates on the dam open and gravity pulls the water through the penstock, a pipeline that leads to the turbine. Water builds up pressure as it flows through this pipe. Turbine - The water strikes and turns the large blades of a turbine, which is attached to a generator above it...
also puts the weight in an inefficient position overhead, so you’re forced to realign your arm and torso to keep the load over your center of gravity. These adjustments trickle downhill and require changing your technique in each step of the exercise to stay in a powerful and stable ...
