TANGENTIAL AND NORMAL COMPONENTS / RADIAL AND TRANSVERSE

Imagine Henry is on a fun adventure, walking in a perfect circle. What can we always say about the transverse coordinates and tangential coordinates in this scenario?

• The er direction is identical to en direction.

• The eq direction is perpendicular to the en direction.

• The eq direction is parallel to the er direction.

Figure out the type of motion of the motorcycle zooming around the track.

• Curvilinear Motion

• Translational Motion

• Both

Choose the correct tangential and normal direction.

• 
• 

Choose the correct formula to calculate normal acceleration.

• 
• 
• 

Based on this diagram, identify the correct radial and angular positions.

Imagine Henry and Grace are at a carnival, riding a carousel. The normal acceleration is much higher than the tangential acceleration. What would happen if, for a given tangential velocity and acceleration, the arm radius of the carousel was doubled?

• The accelerations would remain the same

• The an would increase and the at would decrease

• The an and at would both increase

• The an would decrease
