1st P - Conservation of Mechanical Energy

Front

What is the formula for calculating gravitational potential energy (GPE)?

Back

GPE = m * g * h, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the unit of gravitational potential energy?

Back

Joules (J)

Front

What is kinetic energy (KE)?

Back

The energy an object possesses due to its motion, calculated as KE = 0.5 * m * v^2, where m is mass and v is velocity.

Front

What is the unit of kinetic energy?

Back

Joules (J)

Front

How does the height of an object affect its gravitational potential energy?

Back

The higher the object, the greater its gravitational potential energy.

Front

What happens to the total mechanical energy in a closed system?

Back

The total mechanical energy (sum of potential and kinetic energy) remains constant.

Front

What is the relationship between potential energy and kinetic energy in a pendulum?

Back

As the pendulum swings, potential energy decreases while kinetic energy increases, and vice versa.

Front

What factors affect gravitational potential energy?

Back

Mass of the object, height above the ground, and acceleration due to gravity.

Front

If an object is lifted to a higher position without changing its mass, what happens to its gravitational potential energy?

Back

It increases.

Front

What is the effect of doubling the mass of an object on its gravitational potential energy?

Back

The gravitational potential energy also doubles.
