In psychology, frustration<span> is a common </span>emotional<span> response to opposition. 
Related to </span>anger<span> and </span>disappointment<span>, frustration arises from the perceived resistance to the fulfilment of an individual's </span>will<span> or goal </span><span>and is likely to increase when a will or goal is denied or blocked. 
There are two types of frustration; internal and external. Internal frustration may arise from challenges in fulfilling </span>personal goals<span>, </span>desires<span>, instinctual drives and needs, or dealing with perceived </span>deficiencies<span>, such as a lack of </span>confidence<span> or </span>fear<span> of social situations. 
</span>
Conflict<span>, such as when one has competing goals that interfere with one another, can also be an internal source of frustration and can create </span>cognitive dissonance<span>. 
External causes of frustration involve conditions outside of an individual's control, such as a physical roadblock, a difficult task, or the perception of wasting time.

The normal force(the force pushing up from a flat surface) is equal to the force of gravity (the force pushing down on the object) at 5N so they cancel each other out. The other two forces are going in opposite directions, one positive and one negative. Subtracting 10N-5N would give you the amount of force that is not canceled (5N) in the direction of the biggest force (to the left)
