NEWTONS FIRST LAW OF MOTION

definition: An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

interpretation: An object just does what its doing until acted upon. eg: bowling balls(object) tend to keep rolling(stay in motion) until they hit pins.

Sample Problem: If a ball is rolling down the street at 18 mph (headed north), if it continues in that direction, what speed will it be going in 30 minutes if it isnt acted upon?
