The correct response is: The parachute's upward force resists gravity's downward force.
During the landing, there are two main forces acting on the spacecraft with the parachute:
1. Gravity's downward force: Gravity pulls the spacecraft downwards towards the Earth. This force is acting on the spacecraft and the parachute.
2. The parachute's upward force: When the parachute is deployed, it creates air resistance or drag. This force opposes the downward force of gravity, slowing down the spacecraft's descent and allowing for a safe landing. The upward force exerted by the parachute helps to counteract the effects of gravity, reducing the overall acceleration of the spacecraft.
During the landing of the spacecraft, there are two main forces at play: gravity and the parachute's force.
Gravity is a downward force that pulls the spacecraft towards the Earth. It is responsible for the spacecraft's weight, which is 6.1 million pounds in this case.
The parachute's force comes into play when it is deployed to slow down the descent of the spacecraft. The parachute creates drag, which is a force that opposes the motion of the spacecraft. This force acts in the opposite direction to the velocity of the spacecraft and helps to reduce its speed.
In terms of the given responses, we need to determine the relationship between the directions of the parachute's force and gravity. We know that gravity is acting downward, so we need to determine whether the parachute's force is also acting downward or upward to resist gravity.
Looking at the responses, we can see that only one option matches our understanding: "The parachute’s downward force resists gravity’s upward force." This means that the parachute's force is acting in the same direction as gravity but opposing it. It is working against the upward force of gravity to slow down the spacecraft's descent and help it land safely.
Therefore, the correct answer is: The parachute’s downward force resists gravity’s upward force.
