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
A) because the relation is linear
A) because mass is directly related to acceleration
B) because mass is inversely related to acceleration

Experiences a net force
has zero net force acting on them
experiences greater Normal force than gravity
3

Yes
No
4

apple sauce
no
only on Wednesdays
5
A projectile baseball after it reaches maximum height
looks like a cube
has no net force acting on it
is accelerating more rapidly than it did on the way up
has a net force acting on it
6

The person would go to the barber
The person will accelerate
This person will not accelerate
The tires would slip
7

Is equal in magnitude to the force felt by the windshield
is zero
Is less than the force acting on the windshield
Is greater than the force acting on the windshield
8
Which way will the truck accelerate due to forces from the person in the picture
right
up
left
none
9
A cart is pulled with tension, T at an angle θ. Normal force from the ground...
is equal to the cart's weight
is equal to T
Is greater than the cart's weight
is less the cart's weight
10
A man standing in an elevator moving with constant speed upwards...
experiences greater Normal force than gravity
has zero net force acting on them
has a dashing mustache
Experiences a net force
11
If friction is negligible, the net force on the cart is...
mgsinθ
Tcosθ
Tsinθ
T
12
When a car slams its brakes, occupants lunge forward because
They had inertia
the car was old
The force forward was inertia
They had a net force forward
13
immediately AFTER hitting an air-hockey puck on a frictionless plane, it will generally ___
move with constant velocity
increase its inertia
experience a net force
move with increasing velocity
14
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
