Define Newton's Second Law.
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
What is net force?
The vector sum of all forces acting on an object.
What is mass?
A measure of an object's inertia (resistance to acceleration).
Define acceleration.
The rate of change of velocity.
What is a Free-Body Diagram (FBD)?
A visual representation of all forces acting on an object.
Define Newton's Second Law.

The rate of change of velocity.
Define a Free-Body Diagram (FBD).
A visual representation of all the forces acting on an object.
What is gravitational force?
The force of attraction between objects with mass, always pointing downward.
What is normal force?
The force exerted by a surface on an object, perpendicular to the surface.
What are the steps to draw a Free-Body Diagram?
- Isolate the object. 2. Sketch the object. 3. Identify forces acting on the object. 4. Draw force vectors. 5. Label forces. 6. Add a coordinate system (if needed).
How do you apply Newton's Second Law to solve a problem?
- Draw a free-body diagram. 2. Resolve forces into components. 3. Apply in each direction. 4. Solve for the unknown.
What is the first step in solving force problems using free-body diagrams?
Isolate the object of interest by focusing on one object at a time.
What should you do after identifying all the forces acting on an object?
Draw force vectors with arrows representing each force, starting from the object.
What is the final step in creating a free-body diagram?
Add x and y axes if needed for analysis to create a coordinate system.
