Front

If the mass of an object is 600 kg, what is the change in potential energy when it is raised to a height?

Back

Potential energy change can be calculated using the formula PE = mgh.

Front

Back

51 m

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv²

Front

Front

What does the variable 'm' represent in the equations for kinetic and potential energy?

Back

Mass of the object.

Front

What does the variable 'g' represent in the potential energy formula?

Back

Acceleration due to gravity (approximately 9.81 m/s²).

Front

What is the principle of conservation of mechanical energy?

Back

In a closed system, the total mechanical energy remains constant if only conservative forces are acting.
