Further Mechanics

• Accelerating due to change in direction - velocity is vector
• In a horizontal circle, centripetal force acts towards the center
• Velocity acts tangential to the circle
• The magnitude of centrifugal force = mass x (velocity)^2 / radius
• In a vertical circle, the normal reaction force is taken into account - the centripetal force is greatest at the top as it acts with the reaction
• angular velocity can be measured in radians per second
