Indicate (with a T of F) whether the statement is true or false. If false, change the underlined word or phrase to make the statement true. A bicycle moving at 5.0 m/s at sea level has more potential energy than a motionless bicycle at the top of a mountain. Mechanical work is calculated by multiplying the magnitude of a force times the amount of time it is applied. The SI unit for work is the joule. One joule is equivalent to 1N: m in SI units 5 tv MacBook Pro
