You can’t feel this force because the masses of the pencil and paper are so small. Even you exert a gravitational force on other objects. Because your mass is so much less than the mass of the Earth, you can’t feel your gravitational force. Gravity holds our atmosphere, too.

yes there will be a gravitational force acting between any two bodies having Mass.

Is there gravitational force between two students sitting in a classroom? If so, explain why you don’t observe any effects of this force. Yes. the magnitude of the force is extremely small because the masses of the students are small relative to Earth’s mass.

However, a pencil doesn’t depend on gravity at all! So a pencil will work just fine in space (but the graphite shavings that come off the pencil and don’t stick to the paper might float around the space craft forever!) Thanks for being so curious.

Gravity is a force of attraction between objects based on their mass and their distance apart. Why aren’t other objects, like your pencil, being pulled towards you? Gravity isn’t pulling other objects toward me because I haven’t given my force either or have made an action.

“Einstein’s right, at least for now,” said Ghez, a co-lead author of the research. “We can absolutely rule out Newton’s law of gravity. Our observations are consistent with Einstein’s theory of general relativity. However, his theory is definitely showing vulnerability.

One of the most famous equations in mathematics comes from special relativity. The equation — E = mc2 — means “energy equals mass times the speed of light squared.” It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.

What is general relativity? Essentially, it’s a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

After observing the system for two and a half years, four independent tests of general relativity were possible, the most precise (the Shapiro delay) confirming the general relativity prediction within 0.05% (nevertheless the periastron shift per orbit is only about 0.0013% of a circle and thus it is not a higher-order …
