What is the effect of increasing the angle of an inclined plane on the component of gravitational force parallel to the plane?
The component of gravitational force parallel to the plane increases.
What is the effect of friction on the motion of an object?
Friction opposes the motion of the object, causing it to slow down or preventing it from starting to move.
What is the effect of a non-zero net force on an object?
The object accelerates in the direction of the net force, according to Newton's Second Law ().
What is the effect of an object resting on a surface?
The surface exerts a normal force on the object, perpendicular to the surface.
What happens when the tension in a rope pulling an object increases?
The object experiences a greater force in the direction of the tension, potentially increasing its acceleration.
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.
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.
