What determines an object's kinetic energy?
Mass and speed
Weight and speed
Mass and position
Weight and position
Mass and speed
The correct answer is: Mass and speed.
To determine an object's kinetic energy, you need to consider two factors: mass and speed. The equation for kinetic energy is KE = 1/2 * mass * speed^2. Kinetic energy is a measure of the energy an object possesses due to its motion. The higher the mass and the faster the object is moving, the greater its kinetic energy will be.
