What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

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 potential energy, which is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

How does potential energy change as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance or other forces.

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

Back

In a closed system, the total mechanical energy (the sum of potential and kinetic energy) remains constant, assuming no external work is done on the system.

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

Back

In a pendulum, as it swings from its highest point to its lowest point, potential energy is converted into kinetic energy, resulting in maximum kinetic energy at the lowest point and maximum potential energy at the highest points.

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

Back

The potential energy of an object increases with height; the higher the object is positioned, the greater its potential energy due to the increased gravitational force acting on it.

What type of energy is associated with a compressed spring?

Back

A compressed spring possesses elastic potential energy, which is the energy stored in the spring when it is compressed or stretched.

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
