Units Gravity is an acceleration. The acceleration of gravity on the earth's surface is about 9.81 m sÀ2. Gravity anomalies (observed gravitational acceler- ation minus an expected value) are typically much smaller, about 0.5% of the total field. The SI-com- patible unit for gravity ...
4 The acceleration of gravity on the moon is only one-sixth of that on earth. If you hit a baseball on the moon with the same effort (and at the speed and angle) that you would on earth, the ball would land C A the same distance away.B one-sixth as far. C 6 times as far....
Above the Earth's surface, the magnitude of the force on a particle due to the Earth's gravitationalforce i inversely proportional to the square of the distance of the particle from the centre ofthe Earth. The acceleration due to gravity on the surface of the Earth is g and the Earth ...
