Three non co-linear points form a unique circle due to the circumcircle theorem.

• Three non co-linear points uniquely determine a circle according to the circumcircle theorem.

• The center of the circle passing through these three points is the intersection point of the perpendicular bisectors of the line segments joining the points.

• The radius of the circle is the distance from the center to any of the three points.

• For example, points A(1,1), B(2,3), and C(4,2) form a unique circl...read more

The law of conservation of energy can be verified by observing the energy transformations in a simple pendulum system.

• The potential energy of the pendulum is converted to kinetic energy as it swings back and forth.

• At the highest point, the pendulum has maximum potential energy and zero kinetic energy.

• At the lowest point, the pendulum has maximum kinetic energy and zero potential energy.

• The total mechanical energy (potential + kinetic) remains constant throughout the motion, v...read more

The laws of motion are a set of three fundamental principles that describe the relationship between the motion of an object and the forces acting on it.

• First Law (Law of Inertia): An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force.

• Second Law (Law of Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportio...read more
