Newton's second law

In physics, Newton's second law of motion is a relationship between the acceleration of an object and the forces that act on it. The law states that the sum of the forces applied to an object in an inertial frame of reference is the product of its acceleration by its mass.

Her: "Come over"
Me: "I can't, I'm learning physics"
Her: "My parents aren't home"
Me: *applies a constant force on my own body directed towards hers, causing myself to accelerate in her direction according to Newton's second law applied to my body of constant mass in the terrestrial frame of reference, which can be considered as inertial*
