Physics-121 GCU Key Terms and
Concepts Question and answers 100%
correct 2025
Rigid Object - correct answer ✔A non-deformable object, location of particles
that make up the object are constant. (No fluidity)
Torque - correct answer ✔the force of rotation, causes a rigid body to rotate
faster or slower
𝝉=𝒓×𝑭=(𝑟∙𝐹∙sin𝜃, right−hand rule)
Thermal contact - correct answer ✔When energy can be exchanged
between the two objects
Thermal Equilibrium - correct answer ✔When two objects are in thermal
contact and there is no more exchange of energy
Heat - correct answer ✔The exchange of energy caused by a difference in
temperature. Similar to Work.
Zeroth Law of Thermodynamics - correct answer ✔If objects A and B are
separately in thermal equilibrium with a third object C, then A and B are in
thermal equilibrium with each other.
Gas Pressure - correct answer ✔Collisions between gas particles and the
walls of the container
