L8 - Circular motion

What is the value of a full circle in all 3 units?

360^o

1 revolution

2pi radians

How do you convert between the units?

Divide by the known value for the unit you have and multiply by the known value for the unit you want

What is the equation for arc length?

Arc length = radius x angle

The angle must be in radians

What is the equation for tangential velocity?

Tangential velocity = radius x angular velocity

What is the equation for tangential acceleration?

Tangential acceleration = radius x angular acceleration

What is the equation for radial acceleration?

Radial acceleration = radius x (angular velocity)²

For an inverted loop, what is the equation for velocity?

Velocity = sqrt gravity x radius

What is the reaction force of an inverted loop at the top?

0 unless otherwise stated

What is the equation to calculate banking of a turn?

tan (angle) = v² / (radius x gravity)
