Question

the diagram below represents the forces acting upon an upward - 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 force - direction and magnitude

The upward - moving object has an upward force and a downward force. If the upward force is greater than the downward force, the net force is upward and the object is speeding up. If the upward force is less than the downward force, the net force is downward and the object is slowing down. If the two forces are equal, the object has a constant speed.
From the diagram, the upward arrow is longer than the downward arrow, so the upward force is greater than the downward force.

Step2: Determine motion type

Since the upward force is greater than the downward force, the net force is upward. According to Newton's second law ($F = ma$, where $F$ is the net force, $m$ is the mass and $a$ is the acceleration), a non - zero net force in the direction of motion causes the object to accelerate. So the object is speeding up.

Step3: Determine force balance

Balanced forces occur when the net force on an object is zero. Since the upward and downward forces are not equal (the upward force is greater), the object is experiencing unbalanced forces.

Answer:

Is this a speeding up, slowing down, or constant speed motion? Speeding Up
Is the object experiencing balanced or unbalanced forces? Unbalanced
