By observing the bar graph while the skater is in motion without friction, we can conclude that______________.

• As the skater's KE increases their PE and total energy decrease.

• As the skater's KE increases, their PE decreases and total energy remains the same.

• As the skater's KE increases, their PE and total energy increase.

• As the skater's KE increases, their PE increases and total energy remains the same.
