1. When forces are , the net force on an object is zero.
2. An object at rest will remain at rest unless acted upon by an force.
3. The force that pulls all objects towards the center of the Earth is called .
1. Describe the difference between balanced and unbalanced forces. Provide an example of each.
2. Explain how friction can be both a helpful and a hindering force in everyday life.
Consider the image of the triple beam balance below.
1. If the balance shows a reading of 250 grams, are the forces acting on the balance pan balanced or unbalanced? Explain your reasoning.
