Force+and+Motion

===Here are the science objectives for the 2nd Benchmark! These are from the Maryland State Department of Education. Check this site out!===

2. Demonstrate and explain, through a variety of examples, that moving objects will stay in motion at the same speed and in the same direction unless acted on by an unbalanced force.
===3. Investigate and collect data from multiple trials, about the motion that explain the motion that results when the same force acts on objects of different mass; and when different amounts of force act on objects of the same mass.===

4. Recognize and explain that energy can neither be created nor destroyed; rather it changes form or is transferred through the action of forces.
===1. Observe and describe the relationship between the distance an object is moved by a force and the change in its potential energy or kinetic energy, such as in a slingshot, in mechanical toys, the position of an object and its potential energy.===

2. Identify the relationship between the amount of energy transferred (work) to the product of the applied force and the distance moved in the direction of that force.
===3. Identify and describe that simple machines (levers and inclined planes) may reduce the amount of effort required to do work. * Calculate input and output work using force and distance * Demonstrate that input work is always greater than output work===
