1
A man standing in an elevator moving with constant speed upwards...
Experiences a net force
has a dashing mustache
has zero net force acting on them
experiences greater Normal force than gravity
2
A steak rests on a plate on a table. Which is a true comparison of normal forces
The steak pushes the plate < the table pushes the plate
The table pushes the plate > the plate pushes the table
The steak pushes the plate > the table pushes the plate
The table pushes the steak > the table pushes the plate
3
A projectile baseball after it reaches maximum height
is accelerating more rapidly than it did on the way up
looks like a cube
has a net force acting on it
has no net force acting on it
4
A man standing in an elevator that accelerates upwards...
experiences greater Normal force than gravity
has zero net force acting on them
would register a lighter weight standing on a scale
Experiences a net force
5
Which way will the truck accelerate due to forces from the person in the picture
right
none
up
left
6
immediately AFTER hitting an air-hockey puck on a frictionless plane, it will generally ___
move with increasing velocity
experience a net force
move with constant velocity
increase its inertia
7
When a car slams its brakes, occupants lunge forward because
They had a net force forward
The force forward was inertia
They had inertia
the car was old
8
Which graph correctly depicts Newton's 2nd Law for a constant force applied to varied masses?
B) because mass is inversely related to acceleration
A) because mass is directly related to acceleration
None. Neither graph concurs with Newton's 2nd Law
A) because the relation is linear
9
A cart is pulled with tension, T at an angle θ. Normal force from the ground...
is equal to T
is equal to the cart's weight
Is greater than the cart's weight
is less the cart's weight
10
Compare magnitudes of normal force to gravitational force.
Normal Force < Weight
Normal force = weight
gravity is only greater than normal if it slides
Normal force > weight
11
In absence of friction...
The person will accelerate
This person will not accelerate
The tires would slip
The person would go to the barber
12

T
mgsinθ
Tsinθ
Tcosθ
14
Does the fan help propel the cart forward
apple sauce
no
yes
only on Wednesdays
15

is zero
Is less than the force acting on the windshield
Is equal in magnitude to the force felt by the windshield
Is greater than the force acting on the windshield
