What does v = u + at mean?

Final velocity v equals initial velocity u plus acceleration a times time t (SI units: m/s, m/s², s).

What about deceleration?

Use a negative acceleration (e.g. braking).

Calculate final velocity from initial velocity u, acceleration a, and time t: v = u + a×t.

Initial velocity u (m/s)

Acceleration a (m/s²)

Time t (s)

What does v = u + at mean?: Final velocity v equals initial velocity u plus acceleration a times time t (SI units: m/s, m/s², s).
What about deceleration?: Use a negative acceleration (e.g. braking).
