Circular motion equations9/5/2023 A rollercoaster loop is a vertical one which has a few different properties because it is also changing heights, so there is gravitational potential energy associated with it. Examples of common Circular Motion include a seat going around a round-about or a speed bumps. The idea that even though the magnitude isn’t changing, since your direction is changing, you still experience a Force and then an Acceleration. This process is really what Circular Motion is all about. Hence you end up feeling a force because of that acceleration which again is a result of that change in velocity. And when you are changing velocity, you are going to have an acceleration because acceleration equals to a change in velocity.Īcceleration is a change in velocity over time:Īs Newton’s second law tells use, Force is the product of Mass and Acceleration. Because you are potentially going from a straight path and towards your right, since you are changing direction, you are technically changing velocity. What you are changing is your velocity because velocity is a vector, and vectors not only have a magnitude, they also have a direction. You are maintaining a constant speed as you are turning. When you are going on a roundabout, you are not really changing your speed. Or when you are at a roundabout and are taking a turn, and it kind of feels like a force on your body as you are moving away. What is Circular Motion and how does it all work? You all experience Circular Motion - for example moving around in circles, essentially whenever you’re sitting in a car and it’s gone over a speed bump, which has a bit of a curved bit, or semi-circle. GAMSAT almost always has some tricky Section 3 questions on Circular Motion.
