    How do I teach physics over online chat?

    I am going to be teaching a student soon for physics, but she can't meet me personally (she already paid in advance), so she asked if we can do this online. However, physics is a very visual subject, but I don't have a tablet or anything. Is there an online site where the student and I can be in...

    truck suspension - physics?

    Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance y0, the helper spring engages and then helps to support...

    Physics problem help? A ball is traveling horizontally at velocity vi.?

    It's the very last question on my study guide, but I'm not quite sure of the answer. A ball is traveling horizontally at velocity vi. It is then struck by a stick, making it travel vertically at velocity vf, which is less in magnitude than vi. What direction was the force exerted on the ball by...
