Course: High school physics—NGSS (DEPRECATED) > Unit 1. Lesson 1: Force, mass, and acceleration. Newton's first law of motion introduction. Applying Newton's first law of motion. Newton's second law of motion. More on Newton's second law. Newton's second law review. Understand: force, mass, and acceleration. Apply: force, mass, and acceleration.
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.

Acceleration is the rate of change of velocity (a = Δv/Δt). The unit for acceleration is m/s/s, or m/s^2. Acceleration is a vector with magnitude and direction.

Newton's second law of motion states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate.

Acceleration instead measures the change in an object's velocity. The units for acceleration are meters / seconds^2 (meters per second squared). This means that acceleration tells you how much the velocity changes every second.
