Unbalanced Force = Net Force
... Consider a person sliding down a slide at constant velocity. In this example, there is no net force when a mass moves at constant velocity. Although friction is acting on the person, there is no change in velocity and friction is not a net force in this case. Friction is only a net force if it chan ...

... Momentum is a conserved quantity in physics. This means that if you have several objects in a system, perhaps interacting with each other, but not being influenced by forces from outside of the system, then the total momentum of the system does not change over time. However, the separate momenta of ...

... If an object has a large amount of inertia (due to a large mass) it will be harder to make it change its motion (slow down if moving, speed up if at rest, and/or change direction). That inertia does not depend on gravitational force. Objects would still have inertia even if there were no gravita ...
