If both boxes are acted upon by equal net forces, what is the acceleration?

*Mass - The quantity that measures the resistance of an object to changes in its velocity. m, kg.

*Net Force - The product of an object’s mass and acceleration. 𝚺F, N (kg*m/s²)

*Newton’s 2nd law of motion: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. 𝚺F=ma

*Displacement - The directional change in distance of an object. 𝚫x, m

*Velocity - Displacement over time. v, m/s

*Acceleration - Change in velocity over time. a, m/s²

*Newton’s 1st law of motion: If the net force exerted on an object is zero, the object continues in its original state of motion (or non-motion).

As you make your way down and across the board, think of one real world application of Newton's 2nd Law of Motion and post a note of what that is.
