Force, Mass, and Acceleration
Learning Objective
I can describe how Newton's laws relate force, mass, and acceleration.
Key Concepts
Newton's Second Law of Motion states that when a net force acts on an object, the object will accelerate in the direction of that net force.
The formula for Newton's Second Law is F = ma, where F is force in Newtons, m is mass in kilograms, and a is acceleration in meters per second squared.
The weight of an object is the force of gravity on that object, and can be calculated using the formula W = mg, where g is the acceleration due to gravity, which is 9.8 meters per second squared on Earth.
