Acceleration Vector Summary

The video tutorial explains the concept of acceleration, starting with its definition as the time derivative of velocity. It covers the mathematical representation of acceleration and how to draw the acceleration vector, noting that it doesn't always point tangentially to the path. The tutorial also explains how to calculate the magnitude of acceleration using a formula involving its components.

What is the definition of acceleration in terms of velocity?

• The square of velocity

• The inverse of velocity

• The time integral of velocity

• The time derivative of velocity

Which of the following is true about the acceleration vector?

• It is always perpendicular to the velocity vector

• It can point in any direction, not necessarily tangential

• It is always zero

• It must always point tangentially to the path

What does the horizontal component of the acceleration vector represent?

• a T

• a Y

• a Z

• a X

How is the magnitude of the acceleration vector calculated?

• By multiplying the components

• By taking the square root of the sum of the squares of the components

• By subtracting the components

• By adding the components

Which component of acceleration is associated with the out-of-page direction?

• a Z

• a T

• a Y

• a X
