Multiple Choice

In the equation F = mg, what does g represent?

Weight is the gravitational force acting on a mass, found by multiplying the mass by the acceleration due to gravity. The symbol g represents how quickly gravity accelerates a mass near Earth’s surface, not how fast the object is moving (that’s velocity), nor a distance, nor the mass itself. The value of g is about 9.8 m/s^2, so heavier objects have greater weight because the same acceleration acts on more mass.
