Effects of forces outcomes12 objectives
- Understand that forces can cause changes in an object's size and shape.
- Create, analyze, and interpret load-extension graphs for elastic materials, including the relevant experimental methods.
- Calculate the resultant force when two or more forces are applied in the same direction.
- Recognize that an object will stay at rest or move in a straight line at constant speed unless a resultant force acts on it.
- Acknowledge that a resultant force can alter an object's velocity by changing its speed or direction.
- Explain solid friction as the force that opposes motion between two surfaces and can generate heat.
- Understand that friction (drag) occurs on objects moving through liquids.
- Recognize that friction (drag) acts on objects moving through gases, such as air resistance.
- Define the spring constant as the force applied per unit extension and apply the equation F = kx.
- Define and apply the concept of the 'limit of proportionality' in load-extension graphs and identify this point on the graph.
- Recall and apply the equation F = ma, understanding that force and acceleration are in the same direction.
- Qualitatively describe circular motion influenced by a perpendicular force, noting how speed, radius, and mass affect the required force.
