Define and give examples of force: normal, applied, tension, friction, drag, and air resistance (fluid friction).
Give examples of field forces (forces at a distance) and explain how they vary in strength.
Draw a free body (force) diagram for an object with arrows for an applied force, friction, normal force, tension and/or gravity and use it to calculate the net force (vector sum) on an object.
Physics Classroom: Draw Free Body Diagrams (Practice problems at bottom)
Explain what happens to the motion of an object when forces are balanced and when forces are unbalanced.
Explain why projectiles follow a curved path.**
Explain the relationship between force, mass, and acceleration and use this to calculate force, mass, and acceleration (F=ma). This should include calculating an object's weight. (Hint: Weight is the force of gravity. Acceleration of gravity is 9.8 m/s/s)
Explain “interacting force pairs”, name and draw examples of a force pair including the arrows indicating the direction of force. (Newton’s 3rd Law)
Calculate momentum and conservation of momentum.*
