While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector. So a tennis ball thrown to the right with a velocity of 5 m/s, has the exact same kinetic energy as a tennis ball thrown down with a velocity of 5 m/s.

Can constant C always be positive? - Mathematics Stack Exchange

WitrynaExplain. The kinetic energy cannot be negative, since m and v^2 are always positive or zero. The gravitational potential energy can be negative since any level can be chosen to be zero. Can the kinetic energy and potential energy of a system be negative? Kinetic energy can never be a negative value. Kinetic energy can be quantified as one half ... WitrynaWork can be negative! Work is a measurement of energy, so it may seem odd to think … WitrynaF = k q 1 q 2 r 2. 18.7. This equation is known as Coulomb’s law, and it describes the electrostatic force between charged objects. The constant of proportionality k is called Coulomb’s constant. In SI units, the constant k has the value k = 8.99 × 10 9 N ⋅ m 2 /C 2. The direction of the force is along the line joining the centers of the ... coldplay eco
