What is the difference between energy and power?

Energy is the capacity to do work, while power is the rate at which energy is transferred or work is done.

Differentiate between kinetic and potential energy.

Kinetic energy is the energy of motion; potential energy is stored energy due to position or configuration.

Compare conservative and non-conservative forces.

Conservative forces (e.g., gravity) conserve mechanical energy; non-conservative forces (e.g., friction) dissipate energy as heat.

What are the differences between work and energy?

Work is the transfer of energy from one system to another, while energy is the capacity to do work.

What are the differences between energy, work, and power?

Energy: The capacity to do work. | Work: Transfer of energy. | Power: Rate at which work is done or energy is transferred.

What is the difference between kinetic and potential energy?

Kinetic Energy: Energy of motion, K=12mv2K = \frac{1}{2}mv^2K=21​mv2. | Potential Energy: Stored energy due to position or condition, e.g., U=mghU = mghU=mgh or U=12kx2U = \frac{1}{2}kx^2U=21​kx2.

Differentiate between conservative and non-conservative forces.

Conservative Forces: Work done is path-independent (e.g., gravity, spring force). | Non-Conservative Forces: Work done is path-dependent (e.g., friction, air resistance).

Define the Law of Conservation of Energy.

The total energy of an isolated system remains constant; energy can change forms but is neither created nor destroyed.

What is Total Mechanical Energy (TME)?

The sum of potential (U) and kinetic (K) energies in a system: TME=U+KTME = U + KTME=U+K.

Define the Work-Energy Principle.

The net work done on an object equals its change in kinetic energy: Wnet=ΔK=Kf−KiW_{net} = \Delta K = K_f - K_iWnet​=ΔK=Kf​−Ki​.

What is Power?

The rate at which work is done or energy is transferred: P=WtP = \frac{W}{t}P=tW​ or P=ΔEtP = \frac{\Delta E}{t}P=tΔE​.

What are the units for Power?

Watts (W), equivalent to joules per second (J/s).

What is kinetic energy?

Energy possessed by an object due to its motion.

What is potential energy?

Energy stored in an object due to its position or condition.
