a
0 N
b
500 N
c
1000 N

a
Two people pulling on the same side of a wheelbarrow
b

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 32**
According to Newton's Third Law, if a sledgehammer hits a wall with a force of 1000 N, how much force does the wall hit the sledgehammer?
**Answer:** c - 1000 N
Explanation: According to Newton's Third Law, for every action, there is an equal and opposite reaction. Therefore, the wall exerts a force of 1000 N back on the sledgehammer.

**Question 33**
Which of the following would be a situation with unbalanced forces?
**Answer:** a - Two people pulling on the same side of a wheelbarrow
Explanation: This situation creates an unbalanced force because both individuals are applying force in the same direction, which would cause the wheelbarrow to move.

**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?
**Answer:** b - The force of friction on the object is different if it is stationary or not
Explanation: When an object is stationary, it generally experiences static friction, which is typically greater than kinetic friction (the friction acting on a moving object). Hence, it takes more force to start the movement than to maintain it.
