All Flashcards
What is the effect of increasing the net force on an object (with constant mass)?
The acceleration of the object increases.
What is the effect of increasing the mass of an object (with constant net force)?
The acceleration of the object decreases.
What is the effect of tension in a rope pulling on an object?
The object accelerates in the direction of the tension force.
What is the effect of friction acting on a moving object?
The object decelerates, and its motion is opposed.
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.
Differentiate between mass and weight.
Mass: Measure of inertia | Weight: Force due to gravity.
What are the differences between static and kinetic friction?
Static Friction: Prevents motion | Kinetic Friction: Opposes motion.
Compare and contrast applied force and tension force.
Applied Force: External push or pull | Tension Force: Force exerted by a rope or string.
What are the differences between force and acceleration?
Force: A push or pull on an object | Acceleration: The rate of change of velocity.
Compare and contrast mass and inertia.
Mass: A measure of an object's inertia | Inertia: An object's resistance to changes in its state of motion.
