Worksheet 7: Centripetal Motion Questions 1. You are thrust back into your seat because your seat is accelerating forwards while you are trying to continue at the same velocity you were traveling at before. The car exerts a forward force on you, while by Newton’s 2 nd law, you exert a equal and opposity reaction force backwards on the car. 2. Here, a similar thing is happening. The car is accelerating because the direction of the velocity is changing. You however, want to go in a straight line, which if the seat belt didn’t stop you, would lead outside the car, tangent to the path the car is following. This leads you to feel as though you are being thrust to the side of the car, while in actuality you are traveling in a straight line and the car is accerating. 3. As the washing machine spins, objects in the machine are put in motion, which in general, will cause them to move radially outwards. The water will continue unhindered through the holes placed in the cylindrical tub, while the clothes get caught and are forced (in the physics sense) to stay inside the cylindrical tub.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
