1.	Define acceleration. Write the formula for acceleration. A train starting from railway station attains a speed of 45 m/s in 2 minute. Find its acceleration
Answer» "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."
