motion, forces, and models
Investigation #1: Motion and Variables
-Any change of motion requires a force.
-Gravity is the force that pulls objects toward Earth's center.
-A variable is anything you can change that might affect the outcome of an experiment.
-Pendulum experimental data can be graphed to reveal patterns; length determines the number of cycles a pendulum completes in a unit of time.
-Patterns of motion can be observed and can be used to predict motion.
-What variables might affect the number of cycles a pendulum makes in 15 seconds?
-How does changing the mass, length, or release position of a pendulum affect the number of swings the pendulum completes in a unit of time?
-How can we use graphs to predict results?

Investigation #2: Balls, Ramps, and Energy
-Objects in motion have energy. The faster an object is moving, the more kinetic energy it has.
-When objects collide, energy can transfer from one object to another, changing their motion.
-Kinetic energy is energy of motion; potential energy is energy of position. For identical objects at rest, the objects at higher heights have more potential energy than the objects at lower heights.
-The total balance of energy in any system is always equal to the total energy transferred into and out of the system.
-Momentum helps maintain an object’s motion.
-What happens to balls on ramps?
-What happens when objects collide?
-What is the relationship between the starting position on the ramp and the amount of force a ball can apply when it collides with an object?
-What variables affect the momentum of an object?

Investigation #3: Springs and Energy
-Any change of motion requires a force. Each force has a strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give a zero net force (they are balanced).
-The heavier an object is, the greater the force needed to achieve the same change in motion.
-For a given object, a greater force causes a greater change in motion.
-How do the parts of a flipper system work together to launch an object?
-What is the relationship between the length of the flip stick and the distance the object moves?
-What is the relationship between the compression of the spring and the amount of energy transferred to an object?
