Question

Quizplus · Accepted Answer

In order to accelerate the wheelchair, the force used to propel the chair must increase while the mass in the chair remains the same. This is based on Newton's second law of motion, which states that force equals mass times acceleration. To increase acceleration, either force or mass must increase. Since the mass in the chair remains the same, the force used to propel the chair must increase.
