Force+and+Motion

= = == =Misconceptions:=

The amount of work changes when you use a simple machine...you do "less" work. There is no gravity in space or on the moon. There must be an atmosphere to hold you down in order to have gravity. Only planets have gravity. Mass and weight are the same thing. Bigger things fall faster because of gravity. A straight line on a distance/time graph is when objects are going forward steadily. Buoyancy...issues.

=Force and Motion Learning Goals and Standards:=

2-1: Recognize how forces affect motion.

 * //1. The motion of an object is described as a change in position, direction, and speed relative to another object.//**


 * 2.1.A.7.a Describe the circular motion of a moving object as the result of a force acting toward the center
 * 2.1.A.7.b Classify different types of motion (e.g., straight line, projectile, circular, vibrational)
 * 2.1.A.7.c Given an object in motion, calculate its speed (distance/time)
 * 2.1.A.7.d Interpret a line graph representing an object’s motion in terms of distance over time (speed) using metric units

 * Linking Question: What causes changes in motion? **


 * //2. Forces are classified as contact or non-contact forces that can be described in terms of direction and magnitude.//**
 * 2.2.A.7.a Identify and describe the types of forces acting on an object in motion, at rest, floating/sinking (i.e., type of force, direction, amount of force in Newtons)
 * 2.2.A.7.b Compare the forces acting on an object by using a spring scale to measure them to the nearest Newton

 * 2.2.B.7.a Explain every object exerts a gravitational force of attraction on every other object
 * 2.2.B.7.b Recognize an object’s weight is a measure of the gravitational force of a planet/moon acting on that object
 * 2.2.B.7.c Compare the amount of gravitational force acting between objects (which is dependent upon their masses and the distance between them)

//**4. Changes in motion can be predicted by explaining balanced and unbalanced forces acting on an object.**//


 * 2.2.D.7.a Compare the effects of balanced and unbalanced forces (including magnetic, gravity, friction, push or pull) on an object’s motion
 * 2.2.D.7.b Explain that when forces (including magnetic, gravity, friction, push or pull) are balanced, objects are at rest or their motion remains constant
 * 2.2.D.7. c Explain that a change in motion is the result of an unbalanced force acting upon an object
 * 2.2.D.7. d Explain how the acceleration of a moving object is affected by the amount of net force applied and the mass of the object

 * Linking Question: What do forces have to do with work? **

//**5. You can never get more work out of a system than you put into it.**//


 * 2.2.E.7.a Recognize examples of work being done on an object (force applied and distance moved in the direction of the applied force) with and without the use of simple machines
 * 2.2.E.7.b Calculate the amount of work done when a force is applied to an object over a distance (W = F x d)
 * 2.2.E.7.d Recognize the amount of work output is never greater than the amount of work input, with or without the use of a simple machine

 * Linking Question: Do simple machines change the amount of work we do? **

//**6. Simple machines affect the forces applied to an object and/or direction of movement as work is done**//.


 * 2.2.E.7.c Explain how simple machines affect the amount of effort force, distance through which a force is applied, and/or direction of force while doing work
 * 2.2.E.7.e Evaluate simple machine designs to determine which design requires the least amount of effort force and explain why
