A. Explain how the centripetal force acting on the object will change its motion by doing the following:

1. When an object is moving in a rotational motion

Describe (suggested length of 1–3 sentences) how the object is moving before the centripetal force acts on it, including the following:

• trajectory

• velocity

• acceleration

a. Illustrate the direction of the following vectors using demonstrative arrows before the centripetal force is applied to the object:

• trajectory

• velocity

2. Describe (suggested length of 1 paragraph) what a centripetal force is, including the direction in which it acts with respect to the object.

3. Describe (suggested length of 1–4 sentences) the motion of the object when acted on by the centripetal force, including the following:

• trajectory

• change in velocity

• change in speed

• direction of acceleration

a. Illustrate the direction of the following vectors using demonstrative arrows when the centripetal force is applied to the object:

• velocity

• acceleration

• centripetal force
