tennis ball

|
football

notebook

box of 20 textbooks

Explanation:
Detailed explanation-1: -The answer is false. An object with less speed and more mass could potentially have the same Kinetic energy. The equation for Kinetic Energy is: KE = 1/2 mv2. Kinetic energy has a direct relationship with mass, meaning that as mass increases so does the Kinetic Energy of an object. The same is true of velocity.
Detailed explanation-2: -Two objects of varying mass have the same momentum. The least massive of the two objects will have the greatest kinetic energy.
