If an object is at rest, what is its velocity?
0 m/s
The angle at which a projectile should be launched to maximize horizontal distance
45 degrees
A hammer and a feather are dropped at the same time on the moon. They both reach the ground at the same time. Why?
There is no air, so all objects will fall at the same rate
