1. Thursday, October 18 1. Copy homework 2. Answer the following on your bellwork notebook paper (from yesterday): a) What is net force? b) What causes a net force? c) What is the net force of balanced forces? d) How do you find the net force of unbalanced forces on an object?

2. Newton’s First Law of Motion An object at rest will stay at rest and an object in motion will stay in motion at the same speed and direction unless acted upon by an unbalanced force.

4. Newton’s Second Law of Motion A force is related to an object’s mass and acceleration. force equals mass multiplied by acceleration (F = ma) More massive (heavier) objects accelerate more slowly than objects with less mass.

9. Newton’s Third Law of Motion for every action there is an equal and opposite reaction
