1. newtons second law of motion addresses the relationship between what two variables that influence the force on a body?

a. inertia and mass
b. mass and acceleration
c. acceleration and inertia
d. acceleration and velocity

mark for review (will be highlighted on the review page)

Explanation:

Newton's Second Law of Motion is given by the formula \( F = ma \), where \( F \) is force, \( m \) is mass, and \( a \) is acceleration. This law shows that force is directly proportional to both mass and acceleration. Option A: Inertia is related to mass but inertia itself isn't a variable in the force - mass - acceleration relationship here. Option C: Inertia is not a variable in the direct relationship for force as per the second law. Option D: Velocity is not a variable in Newton's Second Law's formula for force; acceleration (change in velocity over time) is. So the two variables related to force in Newton's Second Law are mass and acceleration.

Answer:

B. Mass and acceleration
