Explanation:
Potential energy is the energy obtained by an object due to the position of an object. Whereas kinetic energy is the energy obtained by an object due to its motion.
For example, an ball is placed over a building of height h. Then steps followed to covert its potential energy into kinetic energy are as follows.
Step 1: When ball is at placed over a building of height h, then it has only potential energy and no kinetic energy.
Step 2: A man pushes the ball and it moves in the downward direction.
Step 3: When ball starts to move or fall it gains kinetic energy, that is potential energy now becomes equal to 0.
Similarly, on reaching the ground and after bouncing a few times when it stop moving then kinetic energy converts into potential energy.
Answer:
, pfx = pix + Jx.
Explanation:
The momentum principle tells us that impulse transfers momentum to an object.
If an object has 2 kgm/s of momentum, a 1 kgm/s impulse delivered to the object
increases its momentum to 3 kgm/s. That is, pfx = pix + Jx.
Just as we did with energy, we can represent this “momentum accounting” with a
momentum bar chart. For example, the bar chart of FIGURE 11.6 represents the ball
colliding with a wall in Figure 11.4. Momentum bar charts are a tool for visualizing
an interaction

Explanation:
In my opinion it does. The more water the pot holds, the longer you need to wait for it to freeze. Since there is more water, some parts may not be completely frozen. An experiment you can try is to get an ice cube container and a pot. fill both of them and put them in the freezer for the same amount of time. When you take it out, the ice cubes should be frozen leaving the pot with cold water.
