Question

A train moves from rest to a speed of 27 m/s in 32.5 seconds. What is its acceleration?​

Answer 1

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
