Please explain the questions below in an easy to understand way and short. (Please don’t give me the formula for the explanation because I don’t understand.)

Question

The link to the projectile experiment (if you need it): https://phet.colorado.edu/en/simulation/projectile-motion

What is the effect of increasing or decreasing the altitude where the experiment takes place? Why?

What happens to the velocity vectors on both the x and y axes as the cannonball moves along its path? Why?

What happens to the acceleration vectors on both the x and y axes as the cannonball moves along its path? Why?

What happens to the force vectors on both the x and y axes as the cannonball moves along its path? Why?

Answer 1

1. Acceleration of Gravity decreases with altitude, because the distance from the center of Earth's mass increases.
2. In projectile type motions, the horizontal (x-) velocity does not change, the acceleration and force are zero. Gravity only acts along the vertical (y-) components!
3. Any upward velocity decreases, until the highest point is reached (v_y = 0), after which the velocity increases downward. Acceleration (of Gravity) and Force (Weight of the object) are constant.

Hope this helps ...
