Suppose the grocery cart is at rest, and you push it to accelerate it into
motion.
does theHow
result differ if you pushed with a force of 40 N instead of 20 N
for the same
amount of
time?
The cart ends up moving Hint, displayed below **BLANK** compared
to before.

How does the acceleration that results from the net force
compare withfrom
acceleration the just the 10 N force? ( Correct answers ) The resulting
acceleration
greater than isthan the acceleration produced by the 10 N
force alone.
Suppose two equal forces pull on the box in opposite directions.Which of
these is
about thetrue
net force from two equal forces in opposite directions?
( Correct
The net force
answers
is )
zero.
Suppose two equal forces pull on the box in opposite directions. Forces
acting that
object on ancombine to give zero net force are said to be balanced.
Why would
term that
be appropriate? ( Correct answers ) They cancel each other and
cause zero
acceleratio
n.
