m/s2 means metres per second squared and it means gravity is the accelation of a body towards the centre of the earth.
26 ms-2
acceleration
Weight in a certain place = (mass of the object) x (acceleration of gravity in that place)Weight of that rock, on Earth = (15 kg) x (9.8 meters/sec2) = 147 newtons
acceleration
Gravitational acceleration. It is actually 9.80665 m/s² (acccording to wikipedia). This means that, as a body falls freely under gravity on Earth, it will be accelerating constantly at a rate of 9.80665 m/s².
9.81 m/s2 is the acceleration of an object in free fall, responding only to gravity with no other forces on it, on or near the Earth's surface ... otherwise known as the acceleration of gravity. It's always true on or near the surface of the Earth ... if you can provide those conditions: No other forces except gravity acting on the falling object, including no air resistance !

F = m A = (70) (9.8) = 686 newtons (154 pounds)Coincidentally, this is the same reading the skydiver sees when he steps on the bathroom scale.
First the acceleration should be 3ms^-2....not 3 ms2...now the force will be 50*3=150 newton...
His MASS is the same on earth and on the moon; it is 102 kg. His WEIGHT is different but mass is the same. On the moon he weighs 102 x 1.62 = 165 Newtons; on earth he weighs 102 x 9.81 = 1000 Newtons
It is 1 Newton.
567 N /9.81 ^(garvity on earth) =57.798 x 1.60 ^(gravity on moon) =92.5 N (rounded to correct number of sig figs)
