Types and Conservation of Energy

What is kinetic energy?

• Potential energy

• Energy an object possesses due to its motion

• Energy from the sun

• Sound energy

Give an example of an object with high potential energy.

• stretched rubber band

• fully wound spring

• loose rubber band

• deflated balloon

What is the formula for calculating kinetic energy?

• KE = 0.5 * m * v

• KE = m * v^2

• KE = 0.5 * m * v^2

• KE = m + v^2

Explain the concept of energy conservation.

• Energy conservation means using less energy to save money

• Energy conservation is the process of creating new energy sources

• Energy conservation involves wasting energy to maintain balance

• Energy conservation is the principle that energy cannot be created or destroyed, only transformed from one form to another.

What are the different forms of potential energy?

• Gravitational, elastic, chemical, and electrical potential energy

• Kinetic, thermal, and nuclear potential energy

• Mechanical, sound, and light potential energy

• Radiant, magnetic, and nuclear potential energy

How does potential energy change with height?

• Fluctuates

• Increases

• Remains constant

• Decreases

What is the unit of measurement for energy?

• liter

• joule

• pound

• meter

What are the factors that affect kinetic energy?

• Height and width

• Volume and density

• Mass and velocity

• Color and temperature

Explain the relationship between potential and kinetic energy.

• Potential energy is converted into kinetic energy when an object is in motion.

• Potential energy and kinetic energy are completely unrelated

• Kinetic energy is converted into potential energy when an object is in motion

• Potential energy is always greater than kinetic energy

What is the relationship between potential energy and work?

• Potential energy is the work done to move an object from one position to another

• Potential energy and work are completely unrelated

• Work is the energy stored in an object at rest

• Potential energy is the energy of an object in motion
