motion equations

• If a car accelerates from 8 m/s to 12 m/s at 2 m/s², what is the distance traveled?

  20 meters
• What force acts against a skydiver as they fall?

  Air resistance
• What happens when air resistance balances the force of gravity?

  The object stops accelerating
• What is the term for the constant velocity reached by falling objects?

  Terminal velocity
• What does terminal velocity depend on?

  It depends on the object's shape
• What is the fluid through which a skydiver falls?

  Air
• What is the effect of shape on terminal velocity?

  Shape affects the force of friction
• What are the steps to calculate distance using the acceleration equation?

  1. Identify initial and final velocities
  2. Determine acceleration and distance
  3. Rearrange the equation if necessary
  4. Substitute values into the equation
  5. Solve for distance
• What are the key concepts related to acceleration in fluids?

  • Objects accelerate at 9.8 m/s² due to gravity
  • Air resistance opposes falling objects
  • Terminal velocity is reached when forces balance
  • Terminal velocity varies with object shape
