What is the effect of increasing the temperature of a gas in a cylinder?
If volume is constant, pressure increases. If pressure is constant, volume increases (Ideal Gas Law).
What is the effect of friction on a sliding object?
It opposes the motion, causing the object to slow down or preventing it from starting to move.
What is the effect of applying an external force to an object?
It causes the object to accelerate in the direction of the net force (Newton's Second Law).
What is the effect of increasing the volume of a gas in a cylinder?
If temperature is constant, pressure decreases. If temperature increases, pressure may remain constant (Ideal Gas Law).
What is the effect of gravity on an object?
It causes the object to accelerate downwards towards the Earth.
What is the effect of buoyant force on an object submerged in fluid?
It reduces the apparent weight of the object.
List the steps to draw a Free-Body Diagram.
1. Identify the object. 2. Sketch the object. 3. Identify all forces. 4. Draw force arrows. 5. Label the forces.
How do you analyze a physical situation using an FBD?
1. Identify forces acting on the object. 2. Relate forces to physical laws (e.g., Newton's Laws). 3. Set up equations based on the FBD.
What is the process of solving for acceleration using an FBD?
1. Draw a FBD. 2. Find the net force (\(F_{net}\)). 3. Use Newton's second law (\(F_{net} = ma\)) to solve for acceleration (a).
What is the process of solving for forces in a gas cylinder?
1. Draw a FBD. 2. Find the gas force using \(F_{gas} = P * A\). 3. Find the piston force using \(F_{piston} = m * a\).
How do you apply conservation of energy in a thermodynamics problem?
1. Identify initial and final states. 2. Write the conservation of energy equation: \(E_i + W = E_f\). 3. Substitute appropriate expressions for energy and work. 4. Solve for the unknown.
What are the key differences between static and kinetic friction?
Static Friction: Prevents motion, variable magnitude up to a maximum. Kinetic Friction: Opposes motion, constant magnitude.
Compare external and internal forces in the context of FBDs.
External Forces: Act on the object from outside the system, included in FBD. Internal Forces: Act within the object, not included in FBD.
Differentiate between applied force and normal force.
Applied Force: A force exerted directly on an object. Normal Force: A reaction force exerted by a surface in response to an object pressing against it.
What is the difference between resistive force and friction?
Resistive Force: Opposes motion through a fluid (like air). Friction: Opposes motion between solid surfaces.
What is the difference between gravitational force and buoyant force?
Gravitational Force: Force of attraction towards the Earth. Buoyant Force: Upward force exerted by a fluid on an object.
