i cant find the answer! I think it is blanced
I think it's friction.
Friction... Right?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
A force is needed to start something moving and to stop it once it is moving. A force can make something speed up or slow down. Friction is a force generated when surfaces move across each other.
Objects start out as either a rest or moving. If they are at rest, they require a force to be applied for them to start moving. If they are moving, they require a force to either slow them down or to make them stop. That means that once something starts moving, it will move forever, unless a force slows it down. The catch is that the force can be friction.
Gravity
Inertia
Inertia
a force and inertia
A force or acceleration
Objects move if they have momentum. Momentum is gained via an applied force. Therefore objects start or stop moving when a net force is working on them.
Sticky friction.
Unbalanced force is a type of force that causes an object to start moving.
It will stay at rest and only start moving if a force is applied.
