Question

the diagram below represents the forces acting upon a rightward - moving object. each arrow represents a force; the length of the arrow represents the strength of the force. is this a speeding up, slowing down, or constant speed motion? speeding up slowing down constant speed is the object experiencing balanced or unbalanced forces? balanced unbalanced

Explanation:

Step1: Analyze vertical forces

Vertical forces (up - down) are equal in length (strength) and opposite in direction. So, \(F_{up}=F_{down}\), vertical forces are balanced.

Step2: Analyze horizontal forces

Horizontal forces: right - ward force is longer (stronger) than left - ward force. So, \(F_{right}>F_{left}\), net horizontal force \(F_{net}=F_{right}-F_{left}
eq0\).

Step3: Determine motion type

Since there is a non - zero net horizontal force in the direction of motion (right - ward), according to Newton's second law \(F = ma\) (\(F\) is net force, \(m\) is mass, \(a\) is acceleration), the object has an acceleration in the direction of motion. So, it is speeding up.

Step4: Determine force balance

Because \(F_{net}
eq0\) (due to unbalanced horizontal forces, vertical forces are balanced but horizontal are not), the object experiences unbalanced forces.

Answer:

Speeding Up
Unbalanced
