What is gravity?

• A resistance to change. 

• A force that attracts and repels objects.

• A force that pulls objects "in" or together.

• A force that causes objects in motion to stay in motion.

What is inertia? 

• A force that attracts and repels objects. 

• An object in motion that was to stay in a straight path unless it is acted upon by another force. 

• A force that pulls objects "in" or together. 

• A force that is measured in Newtons. 

To change the motion of an object, inertia must be overcome by a __________ acting on the object.

• temperature

• speed

• force

• velocity
