Question

match the type of energy to its description. electrical energy a type of energy involving charged particles mechanical energy energy of motion chemical energy a type of energy involving an object in a high position compared to a lower position gravitational energy a type of energy involving the bonding of atoms

Explanation:

• Electrical Energy: It is associated with charged particles as the movement of electrons (charged particles) is what constitutes electrical energy.
• Mechanical Energy: Mechanical energy has two forms - kinetic (energy of motion) and potential. Here, the description "Energy of motion" directly relates to the kinetic part of mechanical energy.
• Chemical Energy: Chemical reactions involve the breaking and forming of bonds between atoms. Chemical energy is stored in these bonds, so “A type of energy involving the bonding of atoms” matches chemical energy.
• Gravitational Energy: Gravitational potential energy is given by \(U = mgh\) (where \(m\) is mass, \(g\) is acceleration due to gravity, \(h\) is height). An object in a high position compared to a lower position has gravitational potential energy.

Answer:

• Electrical Energy: A type of energy involving charged particles
• Mechanical Energy: Energy of motion
• Chemical Energy: A type of energy involving the bonding of atoms
• Gravitational Energy: A type of energy involving an object in a high position compared to a lower position
