Forces and Motion
... • Velocity is how fast an object is moving in one direction. • Velocity = • V=d/t so • T = d/v • On Earth gravity causes objects to fall at 9.8 m/s2 • Notice that an objects mass has little to do with its rate of fall in this example. • However, an objects mass has a lot to do with how quickly an ob ...
