Energy Quiz

What is potential energy?

• Energy possessed by an object due to its position or condition.

• Energy possessed by an object due to its temperature.

• Energy possessed by an object due to its color.

• Energy possessed by an object due to its motion.

Give an example of an object with high potential energy.

• A book on a shelf.

• A roller coaster at the top of a hill

• A car parked on a hill.

• A basketball at the top of a hoop.

What factors affect the potential energy of an object?

• Density and temperature.

• Mass and height or position

• Velocity and time.

• Color and shape.

What is kinetic energy?

• Energy possessed by an object due to its shape.

• Energy possessed by an object due to its motion.

• Energy possessed by an object due to its temperature.

• Energy possessed by an object due to its position.

What is the formula to calculate kinetic energy?

• KE = mass * velocity

• KE = 1/2 * mass * velocity

• KE = mass * velocity^2

• KE = 1/2 * mass * velocity^2

Give an example of an object with high kinetic energy.

• tree

• bicycle

• train

• car

What factors affect the kinetic energy of an object?

• volume and acceleration

• density and temperature

• force and displacement

• mass and velocity

What is the relationship between potential and kinetic energy?

• They are inversely proportional.

• They are unrelated.

• They are equal in magnitude.

• They are interconvertible

Explain the concept of conservation of energy.

• Energy can be both created and destroyed.

• Energy can be destroyed but not created.

• Energy cannot be created or destroyed, only transferred or transformed.

• Energy can be created but not destroyed.

How does energy transfer between potential and kinetic forms?

• Energy is created in the process.

• Energy is destroyed in the process.

• Conversion of potential energy to kinetic energy or vice versa

• Energy is transferred through sound waves.
