Does gravity affect centripetal force? Linear Motion: Newton's laws of motion tell us that, absent an unbalanced force, objects will move in a straight line (with constant velocity). This means, that when we see an object traveling in a circle, there must be some force at work to make ...

Moreover, if you apply a force in the direction of travel, you're doing work (I guess you'll learn about this later) so to preserve energy you need to keep putting energy in - which the boy does but when he stops holding the ball, he can't. Why does i...
50Gravity Does Not ExistThe speed of light is always the same. Because this speed is absolute, time is relative: a moving clock is seen to tick more slowly than the same clock standing still with respect to the observer. This is called time dila-tion, and the equation describing it shows...

Dark matter can refer toany substance which interacts predominantly via gravity with visible matter(e.g., stars and planets). Hence in principle it need not be composed of a new type of fundamental particle but could, at least in part, be made up of standard baryonic matter, such as proto...
If mass actually pulled things together, Jupiter could have no rings, etc – everything would be stuck together! Gravity is a push from all around, a planet is like a submarine – pressure all around. What kind of physicist is this guy that has formulas and...
and specific gravity also are available. When viscosity information is desired, the meter pressure drop needs to be measured. Other features may require information to be pre-programmed into the transmitter memory. In addition, transmitters have other hardware and software options, which allow the us...

Although the moon is our only permanent natural satellite, astronomers have discovered many other near-Earth objects that could be considered honorary ‘mini’ moons. These fall into a few groups. First there are temporary satellites; objects that have been captured by Earth’s gravity, putting th...
