Conservation of Energy & Total Mechanical Energy

Front

What does the Law of Conservation of Energy state?

Back

Energy cannot be created or destroyed, it can only be transformed.

Front

At which point on a roller coaster is the kinetic energy at its maximum?

Back

Point C.

Front

What is the Total Mechanical Energy at point A if it is 500,000 J?

Back

500,000 J.

Front

What happens to potential energy (PE) and kinetic energy (KE) when a ball goes from the highest position to the lowest position?

Back

The PE decreases while KE increases.

Front

At which point on a roller coaster is the gravitational potential energy at its maximum?

Back

Point A.

Front

Define Total Mechanical Energy.

Back

Total Mechanical Energy is the sum of potential energy and kinetic energy in a system.

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is Potential Energy (PE)?

Back

Potential Energy is the energy stored in an object due to its position or configuration, commonly gravitational PE = mgh.

Front

How does energy transform in a pendulum?

Back

In a pendulum, energy transforms between potential energy at the highest points and kinetic energy at the lowest point.

Front

What is the formula for calculating Total Mechanical Energy?

Back

Total Mechanical Energy (TME) = Potential Energy (PE) + Kinetic Energy (KE).
