Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its ---------------- energy increases and its ---------------------------- decreases.
Answer:
Suppose you are shooting a basketball toward a hoop. As the ball rises in the air, its -------Potential --------- energy increases and its -----------kinetic----------------- decreases.
Explanation:
Kinetic energy is the energy of movement or change. Potential energy is the energy a system has as a result of being able to undergo some change. ... As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
How can a charged balloon attract a wall without any contact?
The positive charges of the uncharged wall move to the outside.
The wall changes shape and the positive charges move to the inside.
The negatively charged balloon repels and moves away from the wall.
A positive charge in the balloon attracts the negative charges in the wall.
Answer:
Because it is charged with the opposite type of energy to the wall.
Answer: A
Explanation: The positive charges of the uncharged wall move to the outside.

Compare how a positively charged object and a negatively charged object will react when each is placed separately near an uncharged object.
Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is being applied by something in the environment so that the forces are balanced.
The diagram below shows a box lying on a wedge. Two opposite forces are acting on the box. (1 point)
