Calculating Uniform Acceleration

Question 1

What is the formula for final speed?

Answer 1

(final speed(v))² = (initial speed(u))² + (2 × acceleration × distance moved)

v^2 = u^2 + 2as

v² = u² + 2as

Question 2

What does ‘s’ represent in the formula?

Answer 2

’s’ represents the distance moved in metres (m).

Question 3

What does ‘u’ represent in the formula?

Answer 3

‘u’ represents the initial speed in metres per second (m/s).

Question 4

What does ‘v’ represent in the formula?

Answer 4

‘v’ represents the final speed in metres per second (m/s).

Question 5

What does ‘a’ represent in the formula?

Answer 5

‘a’ represents the acceleration in metres per second squared (m/s²).
