You can use 10 when you only need a rough answer. Use 9.8 when you want your
answer to be more accurate, and if you want it still more accurate, then look up a
more accurate number for the acceleraiton of gravity. (9.8 is a rounded figure.)

How much work does gravity do to a 10kg going 5m up?
Well if we use work = force * distance we have the distance but not the force. We have to use another equation f=ma (force = mass*acceleration) where the acceleration is gravity (9.8 m/s or 10 if you are rounding). Not using rounding: m=10 a=9.8 therefore 10*9.8=98N=force We then input that into our work formula: force = 98 distance = 5 therefore 98*5 = 490J = work without rounding that would simply be 500J Hope this helps!
If an object has a mass of 10 kilograms how much does it weigh?
Near Earth's surface, it would weigh about 98 newton.Weight = mass x gravity And, close to Earth, the gravitational field ("gravity") is about 9.8 newton/kilogram.
What is the mass of a 98 newtons on earth?
10 kilograms.
What is the velocity of a quarter dropped from a tower after 10 seconds?
Since velocity increases about 10 m/s every second (due to gravity), it'd be about 100 m/s. However, that number's fairly approximate and ignores air resistance.
Ten seconds after starting from rest an object on earth falling freely downward will have a speed of about what?
It depends on how long it has been falling and how far it fell. Use equations: [change in] v = a * t [change in] y = v [initial] * t + 1/2 * a * t^2 ----- v = velocity (in m/s) a = acceleration (in m/s^2); for free fall, it's 9.81 m/s^2 t = time (in s) y = vertical displacement (in m)

What Force exerted by a rope on a 10kg mass that is hanging from the rope?
Force = mass X gravity therefore, 10 X 9.8 = 98 N ==================== -- Assuming that this is all happening near the earth, the 10 kg mass weighs 98 newtons. That means the force of gravity on it is 98 newtons, pointing straight down. -- Since it's just hanging there motionless and not accelerating either up or down, the net vertical force on it must be zero. -- The only other force on it besides gravity is the tension in the rope. -- In order for all the vertical forces on it to add up to zero, the tension in the rope must be exactly equal and opposite to the force of gravity ... 98 newtons pointing straight up.

What force causes a object to be heavy?
Gravity makes things heavy. Weight is the effect of gravity on an object's mass. That's the amount of stuff it's made of. The more mass something has, the more gravity tugs it down and the heavier it isWeight is calculated as mass times gravity. Therefore, an object with a mass of 10 kg., in a gravity of 9.8 m/sec2 (approximate value of Earth's gravity) will weigh 98 Newton.Mass also affects intertia. The more mass, the more inertia (resistance to acceleration).What actually gives objects their mass is still a subject of active research. If they ever discover it, the answer will probably be quite complicated.
