Gravity Questions
- Can gravity form waves?
- Can you go fast enough to get enough mass to become a black hole?
- Do I weigh less on the equator than at the North Pole?
- Does every black hole contain a singularity?
- Does the influence of gravity extend out forever?
In this regard, how do you calculate gravitational force Class 9?
The three equation of motion viz. (iii) v2 – u2 = 2as are true for motion of objects under gravity. For free fall, value of acceleration a = g = 9.5 ms–2. If an object is just let fall from a height then in that as u = 0 and a = g = 9.8 m/s2.
Simply so, what are 5 examples of gravity?

What causes gravity?
Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
What is gravitational force Question Answer?
Answer: Solution : Gravitational force is the force of attraction on a body by earth.
What is gravitational force write its formula?
gravitational force = \frac{(gravitational constant) (mass of object 1) (mass of object 2)}{(distance between objects)^{2}}
What is the speed of the gravity?
The best results, at the present time, tell us that the speed of gravity is between 2.993 × 10^8 and 3.003 × 10^8 meters per second, which is an amazing confirmation of General Relativity and a terrible difficulty for alternative theories of gravity that don’t reduce to General Relativity! (Sorry, Newton!)
What is the value of G?
G is the universal gravitational constant, G = 6.674×10–11m3kg–1s–2. M is the mass of the massive body measured using kg. R is the radius of the massive body measured using m. g is the acceleration due to gravity measured using m/s2.
Who discovered gravitational force?
Why does mass cause gravity?
According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons.
