Q: What is the formula for finding the kinetic energy of an object ?
  • A. ma
  • B. 1/2mv ²
  • C. mgh
  • D. 1/2mv⁻ ²
Correct Answer: Option B - Kinetic energy of an object is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v² Where m is mass and v is velocity.
B. Kinetic energy of an object is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v² Where m is mass and v is velocity.
