TME and Power

Front

What is Total Mechanical Energy?

Back

Total Mechanical Energy is the sum of potential energy and kinetic energy in a system. It remains constant in a closed system without external forces.

Front

How is Power defined in physics?

Back

Power is the rate at which work is done or energy is transferred over time. It is measured in watts (W).

Front

What is the formula to calculate Power?

Back

Power (P) = Work (W) / Time (t) where Work is measured in joules and Time in seconds.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. It is often associated with gravitational energy.

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What happens to Total Mechanical Energy in a closed system?

Back

In a closed system, Total Mechanical Energy remains constant, meaning it is conserved.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object due to its motion. It depends on the mass and velocity of the object.

Front

What is the formula for calculating Kinetic Energy?

Back

Kinetic Energy (KE) = 0.5 × mass (m) × velocity (v)².

Front

How does the Total Mechanical Energy change when an object falls?

Back

The Total Mechanical Energy remains constant; potential energy converts to kinetic energy as the object falls.

Front

What is the relationship between work and energy?

Back

Work is done when energy is transferred from one system to another, resulting in a change in energy.
