What is the formula? Flashcards
First Equation of Motion: describes how the velocity of an object changes over time under constant acceleration. (Chapter 2)
Second Equation of motion: calculates the displacement of an object when it starts with an initial velocity and undergoes constant acceleration (Chapter 2)
Third Equation of motion: links the final velocity, initial velocity, acceleration, and displacement without involving time. It’s useful for finding one of these variables when you know the others. (chapter 2)
Fourth Equation of motion: This equation calculates the displacement when you know the initial and final velocities and the time. (chapter 2)
