The analysis of motion in physics often involves understanding the relationship between position, velocity, and acceleration of a moving object along a curve. The scenario described involves a bob swinging along a trajectory, with specific points A, B, and C, and observations regarding the velocity vectors and their changes as the bob moves. This discussion will clarify the reasoning behind the statements presented and their implications in kinematic concepts.

First, consider the statement: "The acceleration of point A is zero. As point C becomes closer and closer to point A, the change in velocity vector becomes smaller and smaller. Eventually, it becomes zero." This reasoning presumes that the acceleration at point A is zero. However, in the context of motion along a curved path, this is generally not the case unless specific conditions are met. Acceleration in curved motion has two components: tangential acceleration, which affects speed, and centripetal (or radial) acceleration, which causes change in direction.

In scenarios where points are along a curved trajectory, the velocity vector's magnitude and direction change continuously. When the bob approaches point A, if the velocity magnitude diminishes, the tangential acceleration may be negative; if it increases, tangential acceleration is positive. The statement suggests that the acceleration at point A is zero, which could be true if the velocity at A is at an extremum (maximum or minimum), meaning the object transitions from speeding up to slowing down or vice versa. At this precise point, the instantaneous acceleration could indeed be zero, especially if the velocity shifts direction instantaneously. However, generally, motion along a curve involves continuous change in velocity vector, and acceleration may not be zero precisely at point A unless specific conditions are met.

Second, analyze the statement: "At point A, the acceleration makes an angle with the tangent to the trajectory that is greater than 0° but less than 90°, since the object is moving on a curve and speeding up." This reasoning aligns more closely with physics principles related to uniformly curved motion. When an object moves along a curved path, the acceleration vector is typically directed towards the center of curvature (centripetal acceleration) but can also have tangential components if the object accelerates or decelerates.

The claim that the acceleration makes an angle greater than 0° but less than 90° with the tangent suggests that the acceleration vector's direction is neither purely tangential nor purely radial but has components in both directions. When an object speeds up along a curve, the total acceleration vector is inclined such that it has both tangential (aligned with the direction of motion) and radial components. The angle between the acceleration vector and the tangent depends on the relative magnitudes of these components.

To visualize these concepts, arrows indicating the direction of the velocity and acceleration at points A and C are helpful. At point A, if the object is accelerating (speeding up), the acceleration vector will have a significant tangential component in the same direction as the velocity, and possibly a radial component towards the center of curvature. Drawing these arrows helps illustrate that the acceleration vector is inclined at an angle less than 90° to the tangent line if the object is speeding up, because both components are in roughly similar directions, but not necessarily aligned.

In conclusion, the reasoning behind the statements hinges on understanding the nature and components of acceleration during curved motion. The claim that acceleration is zero at a specific point requires that the object reach an extremum in velocity at that instant, which can occur under certain conditions. The assertion that acceleration makes an angle between 0° and 90° with the tangent when speeding up is consistent with principles of physics, where the total acceleration vector combines tangential and radial components during non-uniform circular motion.
