An object moves away from the earth. Consider system A: the object alone, and system B: the object and the earth together. The potential energy for system A _____ and the potential energy for system B _____.  for a is increase for B, is it remain same?

A 5.58 kg object falls freely (ignore air resistance), after being dropped from rest. Determine the initial kinetic energy (in J), the final kinetic energy (in J), and the change in kinetic energy (in J) for the following. (a) the first meter of the fall initial kinetic energy final kinetic energy change in kinetic energy initial kinetic energy final kinetic energy (b) the second meter of the fall 0 X How is the initial kinetic energy for the second segment of travel related to the final kinetic energy for the first segment of travel? J change in kinetic energy 0 J J J 54.684 54.684 X How is the final kinetic energy related to the change in kinetic energy? J 109.368 X Can you determine the change in gravitational potential energy for the object as it falls during the second segment of travel? How is the change in kinetic energy for the second segment of travel related to the change in potential energy for the second segment? J 109.368 X Knowing the initial kinetic energy and the change…

An object with mass 2 kg moves from a location m near the Earth's surface to location m. What is the change in the potential energy of the system consisting of the object plus the Earth? (Assume that the +y axis points vertically up from the ground.) i

A very smooth plank of Length L = 2.0 m is evelated to an angel of beta = 30.0 degree above the horizontal. A small ice cube of mass m = 12g is placed at the top of the plane and let go with zero initial velocity. How long does it take for the ice cube to reach the bottom of the plank? How much work was done by gravity on the ice cube?
