1. Week 1 Vocabulary

2. 1. Motion: A change in position.

3. 2. Newton’s 1st Law of Motion: An object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force. 3. Inertia: The resistance an object has to a change in its state of motion. Also known as Newton’s 1st law of motion. Inertia Video

4. 4. Newton’s 2nd Law of Motion: Acceleration depends on the object’s mass and on the net force acting on the object. F= M x A (Force = Mass x Acceleration) 5. Acceleration: The rate at which velocity changes.

5. 6. Newton’s 3rd Law of Motion: For every action, there is an equal and opposite reaction. 7. Speed: The distance an object travels per unit of time. 8. Constant Speed: Speed does not increase or decrease but remains fixed over time.

6. 9. Velocity: Speed in a given direction. 10
9. Velocity: Speed in a given direction. 10. Direction: The line or course on which something is moving or is aimed to move or along which something is pointing or facing. 11. Position: The point or area occupied by a physical object.

7. 12. Reference Point: Is a place or object used for comparison to determine if something is in motion. 13. Distance: The degree or amount of separation between two points. 14. Slope: The steepness of a line or object. The formula for calculating slope is: Slope= _Rise_ Run
