• True
• False

A --- is an object or a collection of objects.

• system

• object

--- are treated as having no internal structure. 

• system

• object

When forces act on an object in opposite directions and are the same size (magnitude).

• Balanced Forces

• Unbalanced Forces

A force that DOESN’T have an equal and opposite force acting on the same object

• Balanced Forces

• Unbalanced Forces

A force equal to the sum of all forces applied to an object.

The mass of an object is a measure of the amount of matter in a body. 

• The mass of an object is the same as its weight.
• Mass is a measure of the object's volume.
• The mass of an object is a measure of the amount of matter in a body.
• The mass of an object can change based on its location.
