the physics of the carousel
- circular motion
uniform, constant angular rate of rotation and constant speed of the carousel allows riders to spin around the axis of the carousel at a constant speed.
- circular motion formulas
average speed = distance/time = (2+pi+R)/T
where v represents speed
R represents radius
T represents period
- simple harmonic motion
the animals that riders ride on utilises simple harmonic motion that allows them to move up and down vertically. the simple harmonic motion is a type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the directions opposite to that of displacement.
- velocity and speed
the speed of the carousel remains the same as it rotates at a constant speed. however, the velocity magnitude is constant but the velocity direction is changing. acceleration is also taking place due to the changing of directions in velocity. the acceleration has a constant magnitude but varying magnitude. the velocity and acceleration is also always perpendicular.
