Circular

• Angular speed measured in

  radians per second
• Linear speed

  Angular speed x radius
• Acceleration towards centre

  Angular speed ^ 2 x radius and linear speed ^ 2 / radius
• Time period (T)

  2pi / angular velocity
• Force

  mass x angular speed ^ 2 x radius
• Force (rearranged)

  Mass x linear speed ^ 2 / radius
• v = w * r
• T = 2pi / w
• (linear)

  a = v^2 / r
• (angular)

  a = w^2 * r
• (angular):

  f = m * w^2 * r
• (linear):

  f = m * v^2 / r
• What is v?


  Linear velocity
• What is w?

  Angular velocity
