What's happening in this FBD?
Forward acceleration
Braking
at rest
constant velocity
Is it possible to be moving to the left like this and have friction in that direction?
Yes. You have negative acceleration.
Yes. You have a constant velocity
No. The force vectors must always point in the direction of motion
No. You have negative acceleration.

The box on the incline is at rest due to friction. Which of these calculations would allow you to get the frictional force?
mg cos theta
mg sin theta
normal force
mg
The force found perpendicular to a surface is
Normal
Friction
Static
Weight
Why is there no net force in the middle of this graph? This is F to t for an elevator.
There is. You can't trick me.
The elevator is at rest
The elevator is accelerating
The elevator has a constant speed
Is this object in equilibrium?
Yes and it's moving right
Yes and its at rest
No, it's accelerating right
No, it's at rest
Which of these is a correct sum statement for Fx?
Fa - Ff = ma
Fnet = Ff
Fn/Fg
Fa = ma

Forces cause acceleration.
True. Every acceleration requires a force.
True. Every force causes acceleration.
False. Acceleration can occur when there is no net force
False. Only net forces cause acceleration.
A tennis ball is thrown upward by a student so that it leaves their hand at 5.29 m/s. After it leaves their hand, what keeps it moving up?
The initial force of their hand overcame gravity
Nothing. The ball simply has inertia.
gravity keeps it moving up.
It is not actually moving up. That is a construct.
A block of mass 2 kg is placed on a frictionless inclined plane making an angle of 30 degrees with the horizontal. What is the acceleration of the block down the plane?
A) 9.8m/s2
B) 4.9m/s2
C) 5.6m/s2
D) 3.3m/s2
