Gravity is also what gives weight to objects on Earth and keeps us from floating away. It pulls everything towards the center of the Earth, keeping us firmly on the ground. The strength of gravity depends on two things: how big an object is and how far apart objects are. If something ...
It also depends on how close you are to the object; the closer you are, the stronger the gravity. Gravity is very important to our everyday lives. Without Earth's gravity we would fly right off our planet! We'd all have to be strapped down all the time and if you kicked a ball,...
How does gravity change with distance? The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, butdecreases with increasing distance between objects. ...
Gravity. Generally what we expect of others depends on the effect of gravity upon ourselves, what we receive from them depends on the effect of gravity upon them. Sometimes (by chance) the two coincide, often they do not. 重力。通常,我们对别人的期望取决于重力对我们自己的影响,我们从他...
light}. Most of the time we think about gravity as the reason we are walking on the ground rather than floating in the air. We are attracted to the Earth. Gravity is why objects fall to the ground. The strength of the attraction depends on the mass of the two objects and the distance...
What Is Gravity? Every object that has mass exerts a gravitational pull or force on every other mass. The strength of this pull depends on the masses of objects at play. Gravity keeps the planets in orbit around the sun and the moon around the Earth. Hence, we define gravity as: ...
depends on the nature of the experiment. for example, if we crash two cars into each other, we will find that the energy was conserved for the collision regardless of whether we were in one of the cars or standing on the sidewalk. conservation of energy is a physical law and therefore,...

Although the existence of a tropopause is down to ozone, its location depends on other things that influence where the tropospheric and stratospheric gradients meet. By warming the troposphere and cooling the stratosphere, greenhouse gases raise that altitude. Greenhouse ...
(which is a reflection of the energy loss to gravitational radiation) and something called the Shapiro delay. The latter phenomenon occurs because light emitted from the pulsar must travel through the intense gravitational field of the pulsar when exiting the system. This effect depends on the ...
