Question

describe or explain 1 - 2 things you learned about frames of reference, velocity, acceleration, or projectiles that were not asked about on this test. points earned here can replace test points lost above. you must describe or explain - no credit for just listing something. edit view insert format tools table 12pt paragraph

Explanation:

Frames of reference are crucial in understanding motion. For example, velocity is relative to the frame of reference. An object's velocity can appear different depending on whether the observer is stationary or moving. Acceleration is the rate of change of velocity. In projectile - motion, an object's acceleration in the vertical direction is due to gravity (usually \(g = 9.8\ m/s^{2}\) near the Earth's surface), while in the horizontal direction (neglecting air - resistance) there is no acceleration.

Answer:

One thing learned is that velocity is relative to the frame of reference. Another is that in projectile motion, the vertical acceleration is due to gravity and the horizontal acceleration is zero (neglecting air - resistance).
