Objectives of the GACE Physics: Equilibrium & Elasticity Chapter
Both Test I and II of the GACE assessments will address your knowledge and understanding of scientific concepts based on a 6-12th-grade comprehension level of physics in order to determine your ability to teach middle or high school science courses in the state of Georgia. Each test lasts between two and two and a half hours, and both consist of 60 selected-response questions. The topics in this chapter will confirm and enhance your existing knowledge while introducing you to new or unfamiliar concepts tested on the GACE Physics assessments.
Equilibrium and elasticity concepts appear in the Mechanics subarea. Our self-assessment quizzes provided at the end of every lesson will determine how well you can recall the information covered on the exam and also give you insight to the types of questions you'll actually see on test day.
1. Equilibrium: Translational & Rotational
Equilibrium is the state of being balanced physically, and it is an important factor for being in motion. Explore the relationship between motion and equilibrium, focusing on the two types: translational and rotational.
2. Stability & Center of Gravity
Without stability, objects would constantly be prey to the negative effects of gravity and fall over with the slightest applied force. Learn about the definition of stability, its relationship with an object's center of gravity, and the three states of stability.
3. Statics Problem-Solving Methods & Applications
A statics problem is solved when the sums of the forces or torques manipulating an object in static equilibrium are determined. Learn more about static equilibrium and the methods and applications of the seven-step process used to solve statics problems.
4. Simple Machines: Lever, Inclined Plane & Pulley
Simple machines make use of mechanical means to apply force and perform work. Learn about different types of simple machines such as the lever, inclined plane, and pulley, and determine the formula for their mechanical advantage.
5. Tensile and Compressive Stress and Strain Equations
Tensile and compressive stress and strain equations are used to find out how stiff a material is. Learn about stress and strain, tension and compression, elastic modulus and Hooke's law, and the stress-strain curve.
6. Shear and Bulk Stress and Strain Equations
Bulk stress causes a change in the volume of the object or medium and is caused by forces acting on the body from all directions, perpendicular to its surface. Shear stress is caused by forces acting along the object's two parallel surfaces. Learn more about bulk and shear stress, strain equations and what shear modulus is.
