An object is moving in the x direction. What quantity is represented by the slope of a
plot of the object's speed as a function of time? - Answers - Acceleration
One person tosses a ball to another. Define the positive y-direction as vertically upward
and the positive x-direction as left to right. Which choice best describes how a plot of
the ball's x-component of velocity vs. time will appear? lgnore drag. - Answers - The plot
will be a horizontal line indicating that the speed in the x-direction is constant over time.
Recall that in a graph of v vs. t, the slope is the acceleration.
At the surface of the earth, all objects accelerate at 9.8 m/s2. - Answers - False. Objects
will accelerate at 9.8 m/s2 if the force of gravity is the only force acting. Any other forces
acting on the object such as upward tension or drag will affect the acceleration.
Suppose you lay a book on your desk and push horizontally on it with 5 N of force which
causes it to slide across the desk at constant velocity. What is the magnitude of the
friction force acting on the book? - Answers - 5 N
If you push a cart and let it go, it will roll to a stop eventually because of friction. How
does the sign of the work done by friction compare to the that of the initial kinetic energy
of the cart? Define the initial point just after you let go of the cart, and the final point
where the cart stops. - Answers - The work done by friction is negative and the initial
kinetic energy is positive.
The impulse is a useful metric for determining the likelihood of a concussion occurring in
a particular collision. The impulse on an object in a collision can be written two ways: as
the change in... of the object, or as the product of the... of the collision. - Answers -
Momentum, force on the object and duration
When holding your arm out to your side, it tends to rotate about your shoulder joint.
However, you can use the muscles in your arm to hold it stationary in which case it is in
static equilibrium. Which of the following correctly describe the net force and net torque
on your arm when in static equilibrium? - Answers - The net torque and net force on
your arm are both zero.
Archimedes' Principle states that for any solid body immersed in a fluid, the buoyant
force acting on it is equal to the... of the displaced fluid. - Answers - Weight
In a graph of F vs. x, where F is the force exerted by a spring, and x is the extension of
a spring, what is represented by the slope m? (Note that F is plotted on the y axis and x
is plotted on the x-axis) - Answers - m = -k
, Because sound is a wave, increasing the frequency of your voice... the wavelength of
the sound you are generating. - Answers - Decreases
When we hear beats produced by combining two sounds, we are hearing an example of
- Answers - constructive and destructive interference
2) Is the time value when the ball in your video has zero y-velocity the same as the time
value forwhen it is at maximum height? Would you expect them to be the same?
Explain why or why not. - Answers - Yes, the time value when the ball in the video has
zero y-velocity is the same as the timevalue when it is at the maximum height. As the
ball reaches maximum height it slowsdown, the velocity decreases until it reaches 0 m/s
y-velocity ( as the ball stopsmomentarily before falling down), and then it increases
again in the negative direction asit falls down because of gravity. This means at the time
value for maximum height, itwould be the time value for velocity to be zero y-velocity.
2) Which general kinematic equation is most like the fit equation for the x position vs.
time?Which kinematic equation is most like the fit equation for the y position vs. time? -
Answers - The kinematic equation that is the most likely to be the fit equation for the x-
position vs.time is Δx = Vt + ½at^2. Noted, due to the absence of gravitational force in
the x-position,acceleration (a) will be 0 m/s2. On the contrary, due to the downward
motion of the ball in the y-position, the equation for the y-position vs. time will be Δx = Vt
- ½at^2. Thenegative sign is due to the gravitational force and downward motion when
the ball falls,resulting in a negative acceleration (a) or -9.8 m/s2.
2) For the y-velocity vs. time graph, how do you find the y-acceleration from the fit?
What is theacceleration expected to be for such an object in free fall? - Answers - To
find the y-acceleration from the y-velocity vs. time graph, we used the slope
tool.Acceleration is the change in velocity over the change in time. The Y acceleration
wascalculated from Capstone -9.44 m/s^2. The acceleration expected for an object in
freefall is -9.8 m/s^2.
2) One source of error in this experiment is that we ignored the effect of drag. In fact,
themagnitude of the drag force is proportional to the speed of the ball. In light of this
fact, is it safeto assume the magnitude of the drag force on the ball is the same at all
points on its trajectory?Support your answer with your reasoning. - Answers - It should
not be assumed that the drag force at all points on the ball's trajectory is the same
because the drag force will impact the motion as the angle and speed
change.Specifically, the velocity in the y-position changes with the ball movement.
However, thevelocity in the x-position remains constant so the drag force should not
have an impact.
3) From your graph, what is the trend for how the acceleration changes as the system
gets more and more massive (while maintaining constant force)? Is this consistent with
Newton's Second Law? - Answers - Newton's Second Law of Motion states that as
mass increases, the acceleration decreases.That said, the graph shows a downward
