Energy Forms | MCQs

Explanation

Heat is a form of energy, specifically thermal energy, which is transferred from one body to another due to a temperature difference.

It is a type of kinetic energy, where the particles of a substance vibrate or move rapidly, generating heat.

Explanation

Potential energy is stored energy due to an object's position or state.

Examples:

• A stretching spring (elastic potential energy)
• A stone lying at a height (gravitational potential energy)
• A book placed on a table (gravitational potential energy)
• A pressed spring (elastic potential energy)

Explanation

Kinetic energy is the energy of motion, and any object that is moving has kinetic energy.

• A moving car (energy from motion)
• A moving runner (energy from motion)
• A moving bicycle (energy from motion)

Explanation

Potential energy is the stored form of energy in an object, which can be released when the object is moved, stretched, or compressed.

Examples:

• Gravitational potential energy (e.g., a ball at the top of a hill)
• Elastic potential energy (e.g., a stretched rubber band)
• Electrical potential energy (e.g., a charged battery)

Explanation

• Kinetic energy is the energy of motion.
• It is the energy an object possesses when it is in motion, such as a rolling ball, a moving car, or a flying bird.
• The amount of kinetic energy an object has depends on its mass and velocity.

Explanation

• Kinetic energy is the energy an object possesses due to its motion.
• Any moving object, such as a car, a ball, or a person, has kinetic energy.
• The amount of kinetic energy an object has depends on its mass and velocity.

Explanation

• Thermal energy is the form of energy that is transferred from one body to another due to a difference in temperature, and is received from heat.
• It is the energy of motion of particles in a substance, such as atoms or molecules, and is often referred to as "heat energy".
