if i drop an apple while riding on a bus that is moving along a level road, and a pedestrian outside sees me do it... won't the pedestrian see motion at a curved motion downward with an initial vertical velosity?
The concept behind "Apple Dropping on Bus: Motion Curve & Initial Velocity" is to analyze the motion of an apple as it falls from a moving bus. This involves understanding the forces acting on the apple and how they affect its path.
The initial velocity of the bus affects the motion of the apple because it determines the horizontal component of the apple's velocity. This means that the apple will have a horizontal displacement as it falls due to the movement of the bus.
The apple follows a curved path due to the force of gravity pulling it towards the ground. As the apple falls, the force of gravity acts on it at a constant rate, causing it to accelerate towards the ground. This acceleration results in a curved path known as a parabola.
The mass of the apple does not affect its motion in this scenario because we assume that the apple has a constant mass throughout its fall. This means that the force of gravity acting on the apple is constant and therefore its acceleration will also be constant.
Other factors that may affect the motion of the apple include air resistance, wind speed, and any other external forces acting on the apple. However, in this scenario, we assume that these factors are negligible and only consider the force of gravity and the initial velocity of the bus.
