What factors impact the kinetic energy of an object?

Question

Mass and speed

Weight and speed

Mass and height

Weight and height

Answer 1

The kinetic energy of an object is primarily impacted by its mass and speed. The formula for kinetic energy (KE) is given by:

\[ KE = \frac{1}{2} mv^2 \]

where:

• \( KE \) is the kinetic energy,
• \( m \) is the mass of the object,
• \( v \) is the speed of the object.

Thus, the correct answer is mass and speed.
