Question

1. which scenario would be studied by dynamics? the acceleration of a person on a roller coaster the force applied by air resistance to a falling skydiver the distance a satellite moves each hour it is in orbit the time it takes a rocket to travel to mars

Explanation:

Step1: Recall dynamics concept

Dynamics in physics deals with the forces that cause motion and changes in motion.

Step2: Analyze each option

• The acceleration of a person on a roller - coaster involves forces causing changes in velocity (acceleration), which is a topic in dynamics.
• The force applied by air resistance to a falling skydiver is about forces acting on a moving object, related to dynamics.
• The distance a satellite moves each hour in orbit and the time it takes a rocket to travel to Mars are more about kinematics (description of motion without considering forces) rather than dynamics.

Answer:

The acceleration of a person on a roller coaster, the force applied by air resistance to a falling skydiver
