1.

2. Why do we use a wrench of long d3. Can kinetic energy be negative? Give reason.lar velocity?

Answer»

Sincekinetic energyis based on motion, it is always a positive value. If it is not in motion, thekinetic energyof that object is zero.

Kinetic energy cannever be anegativevalue.

Kinetic energy canbe quantified as one half of the mass times the velocity squared (KE =1/2*m*v²).
