Elle is playing with a ball in a bus that moves in a straight line with constant velocity. What can you say about the motion of the ball in the moving bus if Elle throws the ball vertically upwards?.

anonymous · Answer

You're in a system (the bus) where the acceleration is zero (the velocity is constant). Relative to the bus, the horizontal component of the ball's velocity is zero. Relative to the ground, the horizontal component of the ball's velocity is the same as the velocity of the bus.

Relative to the bus, the ball traveled in a straight line up and down under the sole influence of gravity. Relative to the ground, the ball traveled in a parabola because it had a constant initial horizontal velocity and an accelerating vertical velocity.
