Data analysis
part a: claim: the cart will have a change in mechanical energy of 48 / as its au
by 12 m.
ollect evidence about the physical meaning of the area under the line on the graph that can be
used to support the claim above. write an equation (including units) for the area between the force
line and the x-axis between x = 0 m and x = 12 m
evidence: the area under the line of the force vs. displacement graph is equal to
_. this area is also known as the
number units number units number units
physical quantity
done on the object.
reasoning: fill in the blanks of the following statement:
the claim makes sense because the
- done on the cart is also equal to the change in
of the cart.
part b: explain how the graph above could be used to determine the final speed of the cart after 12 m.
