Two people are moving a couch. One pushes with a force of 300N right. The other pulls 250N right. There is a friction force of 100N left. What is the net force applied to the couch?
FNET = 650N right
FNET = 450N right
FNET = 550N left
FNET = 50N left
A car with a mass of 2,000 kg applies a force 3,000N right. There is a friction force of 500N left. What is the acceleration of the car?
a = 1.25 m/s2
a = 1.25 m/s
a = 1.5 m/s2
a = 1.5 m/s
Newton's 2nd Law says that the FNET = mass X acceleration. If you are pushing a 100kg object and you increase the force which of these will DEFINITELY change?
The mass of the object
The force of gravity acting on the object
The inertia of the object
The acceleration of the object
All three spheres exert a gravitational force on eachother. Between which 2 spheres is the Fg strongest?
A and B
A and C
B and C
Which setup--A or B--could you hang the heaviest weight from?
A, the FT on each rope is half of the Fg, so it can handle more weight.
B, the FT on each rope is half of the Fg, so it can handle more weight.
A, the FT on each rope is more than the Fg, so it can handle more weight.
B, the FT on each rope is more than the Fg, so it can handle more weight.
Objects moving in a circular path are always accelerating. Why?
They are speeding up
They are slowing down
They are changing direction
They are experiencing balanced FNET
A car is about to move through a curve. What should the driver do to move in a circular path?
Nothing. Circular paths need FNET = 0
Turn her wheels to apply an FNET to the left outside of the circle
Turn her wheels to apply an FNET to the right toward the center of the circle
Hold wheels straight to apply an FNET straight ahead tangent to the circle

A car speeds up after the light turns green
A car moves through a curve at 70 mph
A car travels down a straight stretch of road at 45 mph
If you want an object to accelerate which of the following MUST change?
The object's potential energy (PE= mgh)
The velocity of the object
The weight of the object (Fw = mg)
The mass of the object
The ticker tape diagram places a dot at the location of a moving object at each second. Based on this diagram, what is the best description for the object's motion?
