Front

What is the energy transformation that occurs when a lamp is turned on?

Back

Electrical energy is transformed into thermal energy, which then transforms into light energy.

Front

How do you calculate kinetic energy?

Back

Kinetic Energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the kinetic energy of an object with a mass of 200 kg and a velocity of 5 m/s?

Back

The kinetic energy is 2,500 J.

Front

What is the formula for gravitational potential energy?

Back

Gravitational Potential Energy (GPE) is calculated using the formula: GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the gravitational potential energy of an object with a mass of 50 kg, gravity of 10 m/s², and height of 6 m?

Back

The gravitational potential energy is 3,000 J.

Front

Define potential energy.

Back

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

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more gravitational potential energy it has.
