I can describe motion. This means I define motion as change in an object’s position over time. This means I explain and calculate speed as equal to distance divided by time. I can interpret a distance-time graph. This means I explain and demonstrate a positive slope as movement away from the starting point as time passes. This means I explain and demonstrate a flat line shows that an object is not moving away from the staring point as time passes. (Speed is equal to 0 m/s.) This means I explain and demonstrate that a steeper slope indicates greater speed and a less steep slope indicates slower speed. This means I explain and demonstrate a negative slope as movement toward the starting point as time passes. This means I plot points on a coordinate plane. This means I explain velocity as speed in a certain direction. This means I explain acceleration as how velocity changes over time. I can describe force. This means I define force as a push or a pull. This means I define net force as the total force acting on an object. This means I identify and describe types of forces like gravity, friction, and contact force. This means I recognize when there is no change in speed or direction, forces are balanced. (Zero net force) This means I recognize when there is a change in speed or direction (velocity), forces are unbalanced. I can describe and apply Newton’s First Law of Motion. This means I explain that when forces are balanced, objects in motion stay in motion at the same velocity and objects at rest stay at rest. This means I explain that a change in motion is the result of an unbalanced force acting upon an object. This means I explain objects will move in a straight line unless acted upon by an unbalanced force. This means I describe and demonstrate centripetal force as the forcethat keeps an object moving in a circle. I can describe and apply Newton’s Second Law of Motion. This means I explain when the same force is applied to objects of different mass, the smaller mass will have greater acceleration. This means I explain when mass is the same, a larger force will cause a greater acceleration than a smaller force. This means I describe and calculate force as mass times acceleration. I can describe and apply Newton’s Third Law of Motion. This means I explain that for every action there is an equal and opposite reaction. This means I identify action and reaction pairs. I can describe work. This means I describe and calculate work as force x distance and give examples. I can describe how simple machines affect work, force, and distance. This means I explain how an inclined plane spreads the work over a greater distance based on the length/steepness of the plane. This means I explain how a lever spreads the work over a greater distance based on the placement of the fulcrum. This means I explain how a pulley spreads the work over a greater distance based on the number of supporting ropes.
