Transformation of Energy

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting potential energy to kinetic energy.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. It is often associated with height and mass.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

At which point in a pendulum's swing is kinetic energy greatest?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

At which point in a pendulum's swing is potential energy greatest?

Back

Potential energy is greatest at the highest points of the swing.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
