Human: Please explain the relationship between gravity and acceleration. Assistant: 
Gravity and acceleration are related because the force of gravity affects the acceleration of an object. Gravity changes the direction and intensity of an object's acceleration. In other words, gravity affects the rate of change of velocity of an object, which produces acceleration. This can be seen in Newton's second law of Motion, which states that the force of gravity applied to an object is equal to the mass of the object times its acceleration. Therefore, any acceleration caused by gravity on the object is dependent on its mass.
