L15

Question 1

The longer the radius of a swing/ angular change

Answer 1

The longer the arc length will be

Question 2

Linear/ tangential velocity

Answer 2

Vt= wr
-w needs to be in rad/s
-radius needs to be in meters

Question 3

Tangential Acceleration

Answer 3

At= delta a x radius
-measured in m/s squared
-delta a needs to be in rad/s squared

Question 4

Centripetal acceleration

Answer 4

If you have angular velocity: Ac= w squared x radius
If you have tangential velocity: Ac= Vt squared/ radius

-can also add these 2 to find resultant acceleration using : a= square root at squared + ac squared
