Gravity's pull on objects is a constant here on Earth (an object will fall at a constant acceleration of 9.8 or 10 m/s2) and it always pulls toward the center of the planet (Note: Gravity decreases as you move far away from the surface of the planet.). We can see how quickly an object gains speed a ...

Equilibrium Problems - Warren Hills Regional School District
... Equilibrium is the mathematical representation of Newton's 1st Law. Basically, it says that when an object is (a) at rest, or (b) moving with a constant velocity, then the sum of the force vectors equals zero (F = 0). Static Equilibrium Static equilibrium occurs when an object is at rest. Although ...
