Question

When the spacecraft falls back to earth a parachute helps it fall safely explain the forces. A. Parachutes upward force resists gravity’s upward force b. Parachute downward force resists gravity’s upward force c. Parachutes upward force resists gravity’s downward force d. Parachutes downward force resists gravity’s downward force

Answer 1

The correct answer is c. Parachute's upward force resists gravity's downward force.

When a spacecraft falls back to Earth, gravity pulls it downward towards the Earth's surface. The force of gravity acts in a downward direction. The purpose of a parachute is to create air resistance or drag as it opens up and catches the air. This drag force acts in an upward direction, opposing the force of gravity. Therefore, the parachute's upward force resists gravity's downward force, slowing down the rate of descent and allowing the spacecraft to fall safely to the ground.
