The three formulas for acceleration are: 1. a = (v - u) / t, where 'a' is acceleration, 'v' is final velocity, 'u' is initial velocity, and 't' is time. This formula calculates the change in velocity over a period. 2. a = F / m, where 'F' is the force applied to an object and 'm' is the mass of the object. This relates acceleration to force and mass (Newton's Second Law). 3. a = 2(s - ut) / t^2, useful when the acceleration is uniform, 's' is the displacement, and the other symbols retain their meanings.
FAQs & Answers
- What is the formula to calculate acceleration from velocity and time? Acceleration can be calculated using the formula a = (v - u) / t, where 'v' is the final velocity, 'u' is the initial velocity, and 't' is the time taken.
- How does Newton's Second Law relate to acceleration? Newton's Second Law states that acceleration equals force divided by mass (a = F / m), showing how force applied to an object affects its acceleration.
- When should the formula a = 2(s - ut) / t² be used? This formula is used to calculate acceleration when it is uniform, with 's' as displacement, 'u' as initial velocity, and 't' as time.
