Name:____________________________ Date:____________ Period: ______ Study Guide Answers Motion: Chapter 1, section 1 & 3 Be able to define and understand Motion- One objects distance from another is changing Reference point- A place or object used for comparison to determine if an object is in motion. Velocity- speed in a given direction Acceleration- The rate velocity changes with time. Speed- The distance an object travels divided by time What are the 3 components of acceleration? *Increasing speed *Decreasing Speed *Changing Direction Newton’s First and Third Law of Motion: Chapter 2, section 1 & 4 Inertia: Resistance to change Unbalance Force: a nonzero net force, which changes an object’s motion Balanced Force: Equal forces acting on an object in opposite directions. Why don’t action and reaction forces cancel out? The forces are applied to different objects, therefore they can’t be combined Explain Newton’s First and Third 1st: An object at rest will remain at rest; an object in motion will remain in motion unless an unbalanced force acts upon it. 3rd: For every action there is an equal and opposite reaction. Energy: Chapter 5, section 1 &2 Know the 2 types of energy Kinetic and Potential Energy List and give an example for each form of energy (6) 1. mechanical energy: a person walking 2. thermal energy: ice cream melts when its thermal energy increases 3. chemical energy: Apple 4. electrical energy: power cords 5. electromagnetic energy: UV radiation 6. nuclear energy: produce electricity, found in stars
