Newton's First Law can be used to explain the movement of objects travelling with uniform motion (constant velocity). For example, when a car travels at a constant speed, the driving force from ...

Between 4 and 7 seconds: the object is travelling at a constant velocity of 8 m/s. It travels 3 × 8 = 24 m. Between 7 and 10 seconds: the object is accelerating at 8 3 = 2 2 3 m / s 2.

Orbital mechanics often sounds intimidating, filled with complex equations, gravity wells, and counterintuitive movements.
