What are the steps to create a free-body diagram?
- Represent the object as a dot. 2. Draw vectors representing all forces acting on the object, starting from the dot. 3. Label each force vector with its magnitude and direction.
How do you choose an appropriate coordinate system for a free-body diagram?
- Identify the direction of acceleration. 2. Align one axis of the coordinate system with the direction of acceleration.
What is the difference between static and kinetic friction?
Static friction: Opposes the start of motion. Kinetic friction: Opposes motion between surfaces already in relative motion.
Differentiate between weight and normal force.
Weight: Force due to gravity acting on an object. Normal Force: Force exerted by a surface perpendicular to the contact area, counteracting the component of the weight perpendicular to the surface.
What are the steps to create a free-body diagram?
- Identify the object of interest. 2. Represent the object as a dot. 3. Draw vectors representing forces acting on the object, originating from the dot. 4. Label each force vector.
How do you simplify problem-solving using a free-body diagram?
- Draw the free-body diagram. 2. Choose a coordinate system. 3. Resolve forces into components along the axes. 4. Apply Newton's laws.
