All Flashcards
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.
In a free-body diagram, what does the length of a force vector represent?
The magnitude of the force.
In a free-body diagram, what does the direction of a force vector represent?
The direction in which the force is acting.
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.
