Question 33

Which of the following would be a situation with unbalanced forces?

a
Two people pulling on the same side of a wheelbarrow
b
A team of players in tug of war pulling on the rope, each team with equal numbers of people pulling with equal strength
c
Two people of opposite sides of a big tire. One pushes the tire and one pulls it with equal force
d
Two people not touching a crate that is sitting stationary
Question 34
Why is it generally easier to push a heavy object that is already moving instead of the same heavy object that is stationary

a
The force of gravity on the object is different if it is stationary or not.
b
The force of friction on the object is different if it is stationary or not
c
The force of the push on the object is different if it is stationary or not
d
The normal force on the object is different if it is stationary or not
Question 35
The table below shows the mass and velocity of four objects. Which object has the least inertia?

a
Z
b
X
c
Y
d
W

1 answer

Question 33: The situation with unbalanced forces is:
a Two people pulling on the same side of a wheelbarrow.
This results in a net force acting in the direction they are pulling, causing the wheelbarrow to move.

Question 34: It is generally easier to push a heavy object that is already moving instead of the same heavy object that is stationary because:
b The force of friction on the object is different if it is stationary or not.
Static friction is typically greater than kinetic friction, making it harder to start the motion of a stationary object compared to maintaining the motion of an already moving object.

Question 35: To determine which object has the least inertia, we look for the object with the least mass, since inertia is directly related to mass. Without the specific table containing the masses, I can't provide a definitive answer. However, the answer would be:
a, b, c, or d depending on which object (Z, X, Y, or W) has the least mass.
