All Flashcards
What happens when the net force on an object is zero?
The object's acceleration is zero (it remains at rest or moves with constant velocity).
What is the effect of increasing the net force on an object?
The object's acceleration increases proportionally.
What happens to acceleration if mass increases and force is constant?
Acceleration decreases.
What is the effect of friction on a moving object?
It opposes the motion, causing deceleration.
What happens when tension is applied to a rope connected to an object?
The object experiences a force in the direction of the rope.
What are the steps to draw a Free-Body Diagram?
- Identify the object. 2. Sketch the object. 3. Identify forces (Gravity, Normal Force, Tension, Friction, Applied Force). 4. Draw force vectors. 5. Label forces. 6. Add coordinate system (if needed).
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.
