Exploring Kinetic and Potential Energy

What is kinetic energy and how is it calculated? (two answers)

• Kinetic energy is calculated using the formula KE = m x v.

• Kinetic energy is the energy of a moving object.

• Kinetic energy is the energy stored in an object's position.

• Kinetic energy is calculated using the formula KE = 0.5 x m x v^2

  
  

Define potential energy and provide its formula.

• It is the energy stored in an object's position.

  PE = Fd

• It is the energy stored in an object's position.

  PE = mgh

• It is the energy due oto an object moving

  PE = mv^2

• PE = 1/2 kx^2

How does mass affect kinetic energy?

• Mass directly affects kinetic energy; increasing mass increases kinetic energy if velocity is constant.

• Increasing mass decreases kinetic energy.

• Kinetic energy is only affected by velocity.

• Mass has no effect on kinetic energy.

What factors influence potential energy in an object?

• Speed, distance, and temperature.

• Volume, pressure, and density.

• Color, shape, and texture.

• Mass, height, and gravity

Explain the relationship between kinetic and potential energy.

• Kinetic energy and potential energy are two forms of energy that can convert into each other, maintaining the total energy in a system.

• Kinetic energy and potential energy are two forms of energy that cannot convert into each other, maintaining the total energy in a system.

• Potential energy can never be converted into kinetic energy.

• Kinetic energy is always greater than potential energy.

Give an example of kinetic energy in everyday life.

• A sleeping dog.

• A parked bicycle.

• A moving car.

• A stationary rock.

What is the unit of measurement for energy in the metric system?

• Calorie

• Watt

• Volt

• Joule

How does height affect potential energy?

• Height directly affects potential energy; higher height results in greater potential energy.

• Potential energy decreases with height.

• Height has no effect on potential energy.

• Potential energy is only affected by mass, not height.

Describe a scenario where potential energy is converted to kinetic energy.

• A person standing still at the edge of a cliff.

• A roller coaster descending from a hill.

• A ball resting at the top of a hill.

• A car accelerating on a flat road.

What is the principle of conservation of energy?

• Energy can only be created from matter.

• Energy can be created and destroyed.

• Energy is always lost in transformations.

• Energy cannot be created or destroyed, only transformed.
