I. INTRODUCTION
Speed, distance, time, and acceleration are all very complex formulas that are interdependent. These formulas are measured in motion data and used to determine the final instantaneous speed, distance, time, and acceleration. Distance and time are two formulas that are used to determine speed and time. For example, distance equals speed multiplied with time given, time equals distance divided by speed, and speed is equals distance divided time. Speed and time are required to determine acceleration. ( This is how they are an interdependent formula.) These complex formulas will benefit you in situations , where as you are trying to find the missing equation value dealing with motion data. For example, in many situations, the problem gives information with only the values of time and distance. You are trying to solve for the speed in the given problem, so in order to determine the speed, you’d have to taken the given information and divide the time by distance. In other situations, you are trying to solve for acceleration, which only initial velocity, time, and acceleration are given. You would have to interrelate the given values and take the initial velocity and add it to the acceleration, multiplied by time, then your data and equations sum up to the final velocity. These formulas and equations, in particular, acceleration and speed, are related to Newton’s first law of motion. This is also known as inertia, inertia is the resistance of any physical object to a change in its state of motion and rest, or the ability of an object to resist any change in its motion. Objects at rest will remain at rest if both acceleration and speed are equal to zero . Newton’s first law of motion states “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” An unbalanced force is when 2 forces...
