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