1. Which quantity is scalar?

Question

momentum
energy***
force
velocity

2. Which option describes a vector quantity?(1 point)
It has magnitude, units, and direction.***
It has magnitude, but no units or direction.
It has no magnitude, units, or direction.
It has magnitude and units, but no direction.

3. A sailboat ends up 7 miles to the west of a pier. Which statement is true about this situation?(1 point)
It describes distance, which is a scalar quantity.
It describes distance, which is a vector quantity.
It describes displacement, which is a vector quantity.***
It describes displacement, which is a scalar quantity.

4. Which statement is true regarding a distance vs. time graph?(1 point)

The graph can include only straight line segments.
The graph should show distance on the vertical axis.
The graph must have a horizontal segment.
The graph needs to start at the origin.***

5. On a distance vs. time graph for an object, a line segment that is sloping upward indicates(1 point)
motion in the negative direction.
that the object is accelerating.***
motion in the positive direction.
that the object is speeding up.

I'm struggle, can someone check my answers?

Answer 1

1. yes
2. yes
3. yes
4. Who says you are at zero x at t = 0? I would have picked time on x axis and distance on y axis.
5. If speed is constant, then distance increases with time. The slope is the constant speed. The one I would pick is motion in the positive direction but that means you are graphing velocity, not speed. If the SLOPE increases, then that is acceleration

Answer 2

All of them are right except 4 and 5. 4 is "The graph should show distance on the vertical axis"
5 is "motion in the positive direction"

Answer 3

Thanks "homie" I can't afford another bad grade and I hope you have a good day. :)
