Question

write a hypothesis about the effect of the fan speed on the acceleration of the cart. use the \if... then... because...\ format and be sure to answer the lesson question: \how does an objects position and velocity change as the object accelerates?\

Explanation:

A hypothesis is an educated - guess. In the context of physics, a faster fan speed means more force on the cart. According to Newton's second law ($F = ma$), more force leads to more acceleration. As an object accelerates, its velocity changes over time and its position changes at an increasing rate.

Answer:

If the fan speed is increased, then the acceleration of the cart will increase because a higher fan speed applies a greater force to the cart, and according to Newton's second law, a greater force results in a greater acceleration. As the object accelerates, its velocity increases over time and its position changes at an increasing rate.
