    Fictitious Force: What Makes It Fictitious?

    Ah! I understand! Thank you both for your help! :D

    Fictitious Force: What Makes It Fictitious?

    I think so... So its fictitious because the force is not placed directly on the object, but is in a manner of speaking a by-product (in your example, of the centripetal force acting on the car)?

    Fictitious Force: What Makes It Fictitious?

    [SOLVED] What is fictitious force? Hi. I was wondering if someone would be able to explain to me what is meant by fictitious force? I know that it is a force that acts on masses in a non-inertial frame of reference. That is to say, the motion of the car from the view of the driver, for...

    Schools UBC, University of Toronto, Queen's or Waterloo for civil engineering?

    I have to say... if you got admitted to Waterloo... you should go there. The Civil Engineering program at Waterloo is a co-op program. Starting from your second year, you alternate between one semester of class and one semester of work placement until you graduate. Which is great! Because you...

    Magnitude of force of box on ramp.

    Thank you so much for your patience alphysicist! :D Okay, so from my previous calculations, I have: FN = mg • cos45º So, Ff = µsFN Ff = 118.91N And FgR = Fg • sin45º FgR = mg • sin 45º FgR = 152.24N So... Since FA - FgR - Ff = 0 ∴ FA = Fgr + Ff FA = 152.45N + 118.91N FA = 271.36N FA...

    Magnitude of force of box on ramp.

    Hi alphysicist, I'm not sure if it looks right, actually. I was thinking maybe I have it wrong, and it should be: Fnet = FA - FgR - Ff = 0 (Since both the gravity component and friction are headed down the ramp, and the applied force is going up the ramp.) Also, I did the calculations for...

    Magnitude of force of box on ramp.

    Hmmm... I'm sure if this is correct, but do you mean... Fnet = FgR + FA - Ff = 0?

    Magnitude of force of box on ramp.

    Thank you for your reply. Um... do you mean the component of the force of gravity acting on the box on the ramp? (FgR) If so... FgR = Fg • sin45º FgR = mg • sin 45º FgR = 152.24N I was thinking about that, but I wasn't sure where I would go next...

    Magnitude of force of box on ramp.

    [SOLVED] Magnitude of force of box on ramp. Hello PF, this is my first post on PH. I am hoping that someone will be able to walk me through the question below. I’d really appreciate your help. Thanks. :smile: So, the question is as follow: A box with a mass of 22 kg is at rest on a ramp...
