Explain the concept of Swing Curve in simple words.

• The swing curve shows the relationship between the length of a pendulum and the time it takes to complete one full swing.

• The swing curve is a term used in baseball to describe the trajectory of a ball after being hit.

• The swing curve is a mathematical equation used to calculate the speed of a swinging object.

• The swing curve is a type of dance move popular in the 1950s.

Describe a real-life example where Swing Curve can be observed.

• Number of students in a classroom

• Temperature of a liquid

• Speed of a moving car

• Demand for a product based on its price

How does the Equal Area Criterion help in maintaining stability in power systems?

• By ensuring that the area under the power-angle curve remains constant

• By increasing the area under the power-angle curve

• By decreasing the area under the power-angle curve

• By ignoring the power-angle curve completely

Explain the Equal Area Criterion in a way that a 1st grader can understand.

• If two shapes have the same perimeter, they are equal in size.

• If two shapes have the same area, they are equal in size.

• If two shapes have the same number of sides, they are equal in size.

• If two shapes have the same color, they are equal in size.
