The relationship among mass force, and acceleration is explained by __ a Newtoris first law of motion b Newton's third law of motion conservation of momentum d Newton's second law of motion

## Step 1<br />The problem is asking us to identify which law of motion explains the relationship among mass, force, and acceleration. <br /><br />## Step 2<br />Newton's second law of motion states that the force acting on an object is equal to the mass of that object times its acceleration. This is often written as \( F = ma \), where \( F \) is the force, \( m \) is the mass, and \( a \) is Step 3<br />This law is the one that directly explains the relationship among mass, force, and acceleration. The other options, Newton's first law of motion, Newton's third law of motion, and conservation of momentum, do not explain this relationship.
