The online circular motion simulations on this page will allow you to deepen your knowledge of circular motion and in particular of two of its variables, velocity and angular acceleration.
Circular motion is the motion in which an object moves around a fixed point in a circular path. This type of motion can be uniform, when the angular velocity is constant, or non-uniform, when the angular velocity varies.
For circular motion to occur, there must be a centripetal acceleration directed towards the center of the circular path. This acceleration is necessary to keep the object in its circular path, because if there were no force acting on the object, it would move in a straight line. The magnitude of the centripetal acceleration depends on the velocity of the object and the radius of the path.
The angular velocity determines how fast the object moves around the fixed point. Angular velocity is measured in radians per second.
The period is the time required for the object to complete one full revolution around the fixed point. The period is related to the angular velocity and the radius of the path by the equation T = 2π/ꙍ, where T is the period and ꙍ is the angular velocity.
Circular motion has many practical applications, such as, for example, the manufacture of wheels, gears and pulleys or the dynamics of planets and satellites. In addition, circular motion is used in physics and engineering to describe the trajectory of subatomic particles and the rotation of molecules and atoms.
These online circular motion simulations will be a great help for you to learn more about this important type of motion.
