Kinetic Energy

• What is kinetic energy?

  The energy of a moving object
• How can kinetic energy be calculated?

  Using the equation: $KE =$$0.5 \times mass \times speed^2$
• What does the variable $m$ represent in the kinetic energy equation?


  Mass of the object
• What does the variable $v$ represent in the kinetic energy equation?


  Speed of the object
• What units are used for mass in the kinetic energy equation?

  Kilograms (kg)
• What units are used for speed in the kinetic energy equation?

  Meters per second (m/s)
• What is the formula for kinetic energy?

  $KE =$$0.5 \times m \times v^2$
• What is the relationship between mass, speed, and kinetic energy?

  Kinetic energy increases with mass and speed
• What is the unit of kinetic energy?

  Joules (J)
• In what context is kinetic energy typically discussed?

  In relation to moving objects
• If an object with a mass of $4 \text{ kg}$ is moving at $5 \text{ m/s}$, what is its kinetic energy?


  $50 \text{ J}$
• If an object with a mass of $10 \text{ kg}$ is moving at $2 \text{ m/s}$, what is its kinetic energy?


  $20 \text{ J}$
