Compare kinetic energy and potential energy.
Kinetic Energy: Energy of motion | Potential Energy: Stored energy due to position or configuration.
Compare scalar and vector quantities.
Scalar: Magnitude only (e.g., kinetic energy) | Vector: Magnitude and direction (e.g., velocity).
Compare the effect of mass and velocity on kinetic energy.
Mass: Kinetic energy is directly proportional to mass. | Velocity: Kinetic energy is proportional to the square of velocity.
Differentiate between scalar and vector quantities.
Scalar: Magnitude only (e.g., kinetic energy). Vector: Magnitude and direction (e.g., velocity).
How does kinetic energy differ when observed from different frames of reference?
Kinetic energy depends on the observer's frame of reference, as velocity changes with the observer's motion.
Compare the effect of doubling mass versus doubling velocity on kinetic energy.
Doubling mass doubles KE. Doubling velocity quadruples KE.
Define translational kinetic energy.
The energy an object possesses due to its motion.
What is a scalar quantity?
A quantity that has magnitude but no direction.
What is the unit of kinetic energy?
Joules (J)
Define 'frame-dependent' in the context of kinetic energy.
Kinetic energy of an object varies depending on the observer's reference frame.
What is an inertial reference frame?
A frame of reference in which an object remains at rest or moves with constant velocity unless acted upon by a force.
