Forces Acting on a Skydiver
- When a skydiver jumps out of an airplane, they experience two primary forces acting on them: the force of gravity (P) and the force of air resistance or friction (Q).
- The force of gravity (P) pulls the skydiver downward towards the Earth.
- The force of air resistance (Q) acts in the opposite direction, upward, and it increases with the skydiver's speed.
EXPLANATION:
- When the skydiver's parachute is opened, the following happens:
- Force P (gravity) remains the same because it is dependent on the mass of the skydiver and the gravitational pull, both of which do not change.
- Force Q (air resistance) increases significantly because the parachute increases the surface area, thereby increasing air resistance.
- Therefore, the correct statement is:
After the parachute opens, force P remains the same while force Q increases.
Therefore, the correct answer is Option 3: After the parachute opens, force P remains the same while force Q increases.
