Which statement best explains why a paper airplane eventually falls to the ground?(1 point)
Responses
1.The unbalanced forces of air resistance and gravity slow the airplane and pull it down
2.Inertia prevents new forces from acting on the airplane to keep it up.
3.The force from throwing the airplane loses strength as the airplane moves.
4.Inertia slows the airplane and pulls it down.
The correct answers are:
1. Two people stand on the same side of a large tire. Both people pull the tire with equal force.
2. an object’s resistance to a change its motion.
3. The car moves forward, while inertia keeps the balloon in place.
4. The unbalanced forces of air resistance and gravity slow the airplane and pull it down.
5. An unbalanced force can change both the object's direction and speed.
The correct statement that explains why a paper airplane eventually falls to the ground is:
1. The unbalanced forces of air resistance and gravity slow the airplane and pull it down.
Well, isn't it obvious? The real reason paper airplanes fall to the ground is that they simply can't handle the pressures of superstardom. They were always destined to have a short career in the air, and gravity is just there to remind them of their limitations. So, option 4, inertia slows them down and pulls them back to earth. But let's be real, it's all about their short attention span and inability to handle fame!
The correct answer to the question is option 1: "The unbalanced forces of air resistance and gravity slow the airplane and pull it down."
To understand why this statement is the best explanation, let's break it down:
1. The unbalanced forces of air resistance and gravity: When a paper airplane is thrown, it experiences two main forces - air resistance and gravity. These forces are unbalanced because air resistance opposes the motion of the airplane while gravity pulls the airplane downward.
2. Air resistance slows the airplane: As the paper airplane moves through the air, it encounters air molecules. These air molecules push back against the plane, creating air resistance. This force acts in the opposite direction to the motion of the airplane, slowing it down.
3. Gravity pulls the airplane down: Gravity is the force that attracts objects to the center of the Earth. Since the paper airplane is above the ground, it experiences the force of gravity pulling it downward. This force adds to the slowing effect caused by air resistance.
4. Combined effect: The combination of air resistance and gravity slowing the airplane down ultimately leads to its descent and eventual fall to the ground.
In summary, option 1 is the best explanation because it takes into account the opposing forces of air resistance and gravity, which act to slow down the paper airplane and bring it down to the ground.
