How an object changes velocity depends on the ____________ of the force exerted on that object.

• force

• velocity

• direction

• horizontality

What can cause a greater change in velocity? A stronger force, or a weaker force?

• weaker

• stronger

What is so important about cause-and-effect relationships?

• It is important that we understand this concept because if the object changes, then we can infer the effect on the object.

• It is important that we understand this concept because if the object flies out of the water, then we can infer the cause.
