Kinetic energy

• If a particle weighs 0.1 grams and a plane weighs 20 tons, which has more kinetic energy at the same speed?

  The plane has more kinetic energy
• How does speed affect kinetic energy?

  Faster objects have more kinetic energy
• How does mass affect kinetic energy when speed is constant?

  More mass means more kinetic energy
• What is the equation for calculating kinetic energy?

  $E_k =$$\frac{1}{2} m v^2$
• What does the 'E' in the kinetic energy equation represent?

  Energy
