1
A man standing in an elevator that accelerates upwards...
would register a lighter weight standing on a scale
has zero net force acting on them
experiences greater Normal force than gravity
Experiences a net force
2
A cart is pulled with tension, T at an angle θ. Normal force from the ground...
Is greater than the cart's weight
is equal to T
is less the cart's weight
is equal to the cart's weight
3
If friction is negligible, the net force on the cart is...
Tsinθ
Tcosθ
mgsinθ
T
4
In absence of friction...
This person will not accelerate
The person will accelerate
The tires would slip
The person would go to the barber
5
A man standing in an elevator moving with constant speed upwards...
experiences greater Normal force than gravity
has zero net force acting on them
Experiences a net force
has a dashing mustache
6
A bug splats on the windshield of a moving vehicle. The force on the bug from the windshield
is zero
Is greater than the force acting on the windshield
Is less than the force acting on the windshield
Is equal in magnitude to the force felt by the windshield
7
Compare magnitudes of normal force to gravitational force.
Normal force > weight
Normal force = weight
Normal Force < Weight
gravity is only greater than normal if it slides
8
Which way will the truck accelerate due to forces from the person in the picture
up
right
left
none
9
A projectile baseball after it reaches maximum height
has a net force acting on it
is accelerating more rapidly than it did on the way up
looks like a cube
has no net force acting on it
10
Which graph correctly depicts Newton's 2nd Law for a constant force applied to varied masses?
A) because the relation is linear
A) because mass is directly related to acceleration
B) because mass is inversely related to acceleration
None. Neither graph concurs with Newton's 2nd Law
11
immediately AFTER hitting an air-hockey puck on a frictionless plane, it will generally ___
experience a net force
move with constant velocity
move with increasing velocity
increase its inertia
12
A block rests on an inclined surface as shown. Is there a non-zero net force on the block?
Yes
No
13
Does the fan help propel the cart forward
yes
only on Wednesdays
apple sauce
no
14
When a car slams its brakes, occupants lunge forward because
They had a net force forward
The force forward was inertia
the car was old
They had inertia
15
A steak rests on a plate on a table. Which is a true comparison of normal forces
The table pushes the steak > the table pushes the plate
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
