Alignment to Standards for DC 1 SC.1.3. The motion of objects can be observed, measured, and changed.
1 SC.1.3.1. Observe and describe that the way to make something move (faster or slower or in a different direction) is by giving it a push or a pull, which is called a force.
1 SC.1.3.2. Explain that the greater the applied force, the greater the change in the motion of the object.
5 SC.5.6. Unbalanced forces cause changes in velocity.
5 SC.5.6.2. Demonstrate that if the forces acting on an object are balanced so that the net force is zero, the object will remain at rest if it is initially at rest or will maintain a constant speed and direction if it is initially moving.
5 SC.5.6.3. Investigate and describe that unbalanced forces cause changes in the speed and/or direction of motion of an object (acceleration).
5 SC.5.6.4. Describe that, for an object moving in a straight line, acceleration, a, is the change in velocity, v, divided by the time, t, that change takes (a = v É t ).
5 SC.5.6.5. Investigate and describe that the greater the net force, F, applied to a body, the greater its acceleration, a. Describe that the greater the mass, m, of an object, the smaller the acceleration produced by a given force.
