Here's a perfect example of a stable and unstable system.
Kicks it up into the air and it falls back down to her, or it could be it was kicked and bounced off another surface like a wall and the force returns it to her.
How does physical weathering compare to natural erosion?Physical weathering is the breakdown of rocks and soil, while natural erosion is the removal of solids (sediment, soil, rock) and occurs with movement. Eosion differs from weathering because it is transferred by wind, water, and ice; gravity has an immense role in erosion; and even living organisms are a key <span>component to erosion because certain species burrow, which disturbs the soil. </span>
Reading of the scale will be given as Normal force on the man
So here we can say that
weight of the mas will be
normal force on the man will be given as
now net force is given by Newton's II law
a = 3.33 m/s^2
so elevator is accelerating downwards with an acceleration a = 3.33 m/s^2
