Conservation of momentum is a myth.
Two girls get into a tug of war over a phone. One girl pulls to the left with a force of 30 N, while the other girl pulls to the right with a force of 35 N. In this situation, are the force balanced or unbalanced?
The forces are balanced
The forces are unbalanced
There is not enough information to tell
I don't think any of the people involved care whether the forces are balanced or not.
A person speeds up while running away from their crazy ex. Are the forces on them balanced or unbalanced?
The forces are balanced
The forces are unbalanced
There is not enough information to tell
Depends on if you mean literally balanced, or mentally balanced.
A tardy student strolls to class by walking at a slow, constant speed in a straight line. Are the forces on them balanced or unbalanced?
The forces are balanced
The forces are unbalanced
There is not enough information to tell
I'm sure they can figure it out while serving detention for being tardy.
Suppose you push an annoying person with a force of 10 N. With what force do they push back on you?
10 N because the forces are equal according to Newton's 3rd law.
0 N, because they would never dare push back on me
0 N, because you shouldn't push anyone, even if they are annoying
10 N, because they always copy everything I do
Two boys get into a fight over the last piece of pizza by pulling on the pizza in opposite directions. In this situation, to find the total force on the pizza, would you add the forces, or subtract them?
Add the forces
Subtract the forces
Neither. Pizza isn't worth fighting over.
It depends on what kind of pizza it is.
A 3 kg object accelerates at 8 m/s. What is the net (total) force on the object? Use F = ma
24 N
2.33 N
5 N
11 N
An object accelerating at 4 m/s/s experiences a force of 40 N. What is the object's mass? Use F = ma
160 kg
10 kg
0 kg
44 kg
A 70 kg boy goes to a larger planet, hoping to weigh more and therefore be more attractive to alien chicks. What will his mass be on the larger planet?
70 kg. Mass doesn't change.
140 kg because the force of gravity is greater
0 kg because he'd be dead on another planet
Alien chicks? That's really wierd...
An 80 kg person wants to lose weight, so they go to the moon. Did they actually lose weight by going to the moon?
Yes, because weight is just the force of gravity
No, because weight doesn't change on other planets
No, because it isn't cool to body-shame people.
They actually gained weight by going to the moon
A student tries to slide across the carpet in a classroom and gets rug burns due to frictional force. If the student's mass decreased, what would have happened to the frictional force?
It would decrease
It would increase
It would stay the same
Who would try to slide on carpet anyway?
A student tries to slide on the carpet in a classroom and gets rug burns due to frictional force. If the floor had been tile (which is smoother than concrete), what would happen to the frictional force?
It would increase
It would decrease
It would stay the same
But it wasn't tile, was it, so they still got burned...
