Question 1: Define acceleration and explain its significance in the context of medical devices such as patient monitoring systems.

Answer: Acceleration is the rate of change of velocity over time, measured in metres per second squared (m/s²). In medical devices, it helps monitor movements such as patient mobility or the acceleration of medical equipment during transport.

Question 2: Describe how acceleration can affect the operation of a medical imaging device during patient movement.

Answer: Uneven acceleration during patient movement can cause blurring in images or misalignment in imaging systems, affecting diagnostic accuracy.

Question 1: A wheelchair accelerates from rest to a speed of 1.5 m/s in 3 seconds. Calculate its acceleration.

Answer: Acceleration = (Final velocity - Initial velocity) / Time = (1.5 m/s - 0) / 3 s = 0.5 m/s²

Question 2: A robotic surgical arm accelerates at 2 m/s² over a distance of 0.8 metres. What is the change in velocity of the arm?

Answer: Using v² = u² + 2as, with u=0: v² = 0 + 2 × 2 m/s² × 0.8 m = 3.2, so v = √3.2 ≈ 1.78 m/s

Question 1: Design a simple experiment to measure the acceleration of a mobile medical cart moving along a corridor. List the variables you would control and safety precautions you would take.

Answer: Students should describe measuring time and change in velocity using sensors or timers, control variables such as load weight and surface type, and ensure safety by securing loose items, wearing appropriate footwear, and avoiding collisions.

Question 1: A patient’s limb is accelerated in a physiotherapy device from 0 to 2 m/s over 4 seconds. The device records a constant acceleration. Describe the data you would expect to see and how it indicates the movement's acceleration.

Answer: A steady increase in velocity over time indicating constant acceleration; the recorded data would show a straight line on a velocity-time graph with a slope corresponding to 0.5 m/s².

Question 1: Explain how understanding acceleration is important in designing safety features for patient transport devices such as stretchers or wheelchairs.

Answer: Knowing acceleration helps engineers design smooth-start and stop mechanisms, reducing shock and injury risk to patients. It also aids in developing safety features like seat belts and shock absorbers that accommodate rapid changes in movement.

Question 2: Multiple Choice: Which of the following best describes the significance of acceleration in medical technology? A) It determines the size of medical devices. B) It affects the speed of drug delivery systems. C) It influences the stability and safety of moving medical equipment. D) It is unrelated to medical technology.

Answer: C) It influences the stability and safety of moving medical equipment.
