Front

What are the three forms of energy transformations observed in a pencil sharpener?

Back

Electrical energy transforms into mechanical energy, which then transforms into sound energy.

Front

Define potential energy.

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.
