Terminal Velocity

Cards (37)

  • What is terminal velocity?
    The constant speed of a falling object
  • What causes an object to accelerate while falling through a fluid?
    The force of gravity acting on the object
  • How does drag force change as an object accelerates through a fluid?
    It increases until it matches the weight force
  • What happens when the drag force equals the weight force?
    The object reaches terminal velocity
  • What is the result when the resultant force on an object is zero?
    The object moves at terminal velocity
  • What is the relationship between drag force and acceleration?
    Drag force increases as acceleration increases
  • What happens to an object when it is released from rest?
    It accelerates due to gravity
  • What forces act on a body during acceleration?
    Gravity and drag force
  • What is the effect of body weight on terminal velocity?
    Heavier objects have higher terminal velocity
  • How does the terminal velocity of an object relate to its mass?
    It increases with greater mass
  • What happens to the forces acting on a body at terminal velocity?
    The forces balance out to zero
  • What is the primary force acting on an object in free fall?
    Gravity
  • What is the role of drag force in terminal velocity?
    It opposes the force of gravity
  • What is the condition for an object to stop accelerating during free fall?
    When drag force equals weight force
  • How does the drag force affect the motion of a falling object?
    It slows down the object's acceleration
  • What is the significance of terminal velocity in physics?
    It represents a state of equilibrium in forces
  • What happens to an object when it reaches terminal velocity?
    It continues to fall at a constant speed
  • What is the effect of fluid density on terminal velocity?
    Higher density fluids increase drag force
  • How does the shape of an object influence its terminal velocity?
    Streamlined shapes reduce drag and increase velocity
  • What is the relationship between terminal velocity and fluid viscosity?
    Higher viscosity increases drag and lowers velocity
  • Why do objects fall at different terminal velocities?
    Due to differences in mass and shape
  • How does terminal velocity relate to the concept of equilibrium?
    It represents a balance of forces acting on the object
  • What is the primary factor that determines the drag force on a falling object?
    The object's speed through the fluid
  • How does terminal velocity affect the time it takes for an object to fall?
    It determines the maximum speed during the fall
  • What happens to the acceleration of an object as it approaches terminal velocity?
    Acceleration decreases until it becomes zero
  • What is the effect of air resistance on falling objects?
    It opposes the motion of the object
  • What is the significance of the term "resultant force" in the context of terminal velocity?
    It indicates the net force acting on the object
  • How does the concept of terminal velocity apply to parachuting?
    Parachutists reach terminal velocity before landing
  • What is the role of gravity in determining terminal velocity?
    It provides the downward force on the object
  • How does terminal velocity relate to the concept of free fall?
    It is the constant speed during free fall
  • What factors can affect the terminal velocity of a skydiver?
    Body position, weight, and clothing type
  • What happens to the drag force as an object accelerates through a fluid?
    It increases until terminal velocity is reached
  • What is the effect of terminal velocity on the motion of a falling object?
    It limits the maximum speed of the object
  • How does the concept of terminal velocity illustrate Newton's first law of motion?
    It shows that an object in motion stays in motion
  • What is the relationship between terminal velocity and the forces acting on an object?
    They balance each other out at terminal velocity
  • How does terminal velocity affect the safety of skydivers?
    It ensures they fall at a safe speed
  • What role does terminal velocity play in the design of parachutes?
    Parachutes increase drag to lower terminal velocity
