Use the data from Table B of your Student Guide to answer the questions. Be sure to round
your answers to the nearest tenth.
What was the acceleration of the cart with Low fan speed? (1) cm/s2
What was the acceleration of the cart with Medium fan speed? (2) cm/s2
What was the acceleration of the cart with High fan speed? (3) cm/s2 - CORRECT
ANSWERS-1) 9.0 cm/s2
2) 12.0 cm/s2
3) 16.0 cm/s2
The graph shows the acceleration of the cart with three different fan speeds. The fan provides
the force necessary to accelerate the cart.
As the fan speed increases, the acceleration of the cart (1)
The type of relationship that exists between the force applied to the cart by the fan and the
acceleration of the cart is (2) relationship. - CORRECT ANSWERS-1) increases
2) a direct
Do the data for the first part of the experiment support or refute the first hypothesis? Be sure to
explain your answer and include how the variables changed in the first part of the experiment. -
CORRECT ANSWERS-The data for the first part of the experiment support the first
hypothesis. As the force applied to the cart increased, the acceleration of the cart increased.
Since the increase in the applied force caused the increase in the cart's acceleration, force and
acceleration are directly proportional to each other, which is in accordance with Newton's
second law.
This experiment was divided into two parts. For the first part of the experiment, (1) was
intentionally manipulated. This was the independent variable. The dependent variable measured
was the (2)
For the second part of the experiment, the (3) was intentionally manipulated. This was the
independent variable. The dependent variable measured was the (4) - CORRECT
ANSWERS-1) force applied to the cart
