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.
Define Free-Body Diagram (FBD).
A visual representation of all external forces acting on an object.
What is Gravitational Force?
The force of attraction between objects with mass, directed towards the center of the Earth.
Define Normal Force.
The force exerted by a surface on an object in contact with it, perpendicular to the surface.
What is Friction?
A force that opposes relative motion between surfaces in contact.
Define Buoyant Force.
An upward force exerted by a fluid that opposes the weight of an immersed object.
What is Applied Force?
A force that is directly applied to an object by another 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.
