Centripetal Acceleration

Centripetal Acceleration

E.Q. What forces act as they move in a circle?

H.P.2B.8 Develop and use models (such as a computer simulation, drawing, or demonstration) and Newton’s Second Law of Motion to construct explanations for why an object moving at a constant speed in a circle is accelerating.

What's your good thing today, how are you (1-10), or Would you rather have a desk job or an outdoor job and WHY?

Multiple Choice

An object moves in a circular path at a constant

speed. Compare the direction of the object's

velocity and acceleration vectors.

• Both vectors point in the same direction

• The vectors point in opposite directions

• The vectors are perpendicular

• The question is meaningless, since the

  acceleration is zero

Multiple Choice

What type of acceleration does an object moving

with constant speed in a circular path experience?

• free fall

• constant acceleration

• linear acceleration

• centripetal acceleration

Multiple Choice

Consider a particle moving with constant speed

such that its acceleration of constant magnitude

is always perpendicular to its velocity.

• It is moving in a straight line

• It is moving in a circle

• It is moving in a parabola

  all of the time
