Front

What is the definition of kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv² (where m is mass and v is velocity).

Back

The kinetic energy increases by a factor of nine.

Front

What is elastic limit?

Back

What is the relationship between mass and momentum?

Back

Momentum is directly proportional to mass (p = mv).
