The spacecraft shown below weighs 6.1 million
pounds. The rocket produces 7.5 million pounds of
thrust.
When the spacecraft falls back to earth, a
parachute helps it fall safely. Explain the forces
acting during this landing.

The parachute's upward force resists gravity's
downward force.
The correct answer is: The parachute's upward force resists gravity's downward force.
To answer this question, we need to understand the concept of forces acting during the landing of a spacecraft with a parachute.
First, let's understand the role of gravity. Gravity is the force that pulls objects towards the center of the Earth. In this case, it is pulling both the spacecraft and the parachute downwards.
Now, let's consider the forces acting on the parachute during the landing. When the parachute is deployed, it creates drag, which is a type of resistance against the motion of the spacecraft. This resistance is caused by the parachute's shape and the air passing through it. As a result, the parachute generates an upward force.
Therefore, the correct answer is: The parachute's upward force resists gravity's downward force.
This means that the upward force generated by the parachute helps to counteract the downward force of gravity, slowing down the fall of the spacecraft and allowing it to land safely.
The correct answer is: The parachute's upward force resists gravity's downward force.
During the landing, the parachute helps in slowing down the descent of the spacecraft by creating air resistance. This air resistance creates an upward force that counteracts the force of gravity pulling the spacecraft downward. This opposing force provided by the parachute allows the spacecraft to descend at a slower and safer speed.
