How are radius, velocity, acceleration, and force related in circular motion?
Many objects—from spinning wheels to the orbits of satellites around the Earth—undergo circular motion. For an object to remain in circular motion, it must experience a centripetal force (and acceleration). In this investigation, you will explore the properties of circular motion at scales similar to that of a mass swung around horizontally at the end of a string.
Part 1: Directions of the velocity, force, and acceleration vectors
Set m = 5.0 kg, r = 5.0 m, and v = 5.0 m/s.
Play the simulation, and then pause it at various positions around the circle.
Sketch the velocity, force, and acceleration vectors for at least five positions distributed around the circle.
