What else can I help you with?
Which term explains whether an objects velocity has increased or decreaseed over time?
Acceleration describes whether an object's velocity has increased or decreased over time. An object has positive acceleration if its velocity is increasing, negative acceleration if its velocity is decreasing, and zero acceleration if its velocity is constant.
What do motionless objects have in common with objects that are moving in a straight line with speed?
Motionless objects and objects moving in a straight line with constant speed both have a constant velocity of zero or a constant velocity in a single direction, respectively. They share the characteristic of having a consistent position relative to a reference point over time.
What are two ways in which an object can have constant velocity uniform motion?
Objects moving in uniform circular motion will have a constant speed, and two objects with the same acceleration have a constant velocity.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
What is the objects acceleration?
The acceleration of an object is the rate at which its velocity is changing over time. It is a vector quantity, meaning it has both magnitude and direction. Acceleration can be positive, negative, or zero, depending on whether the object is speeding up, slowing down, or maintaining a constant velocity.

What happens of there is no friction?
Objects would move with constant velocity or stay at rest.
When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)

Why you never see objects moving with constant velocity unless a net force is applied?
friction
What do baoanced forces do to moving objects?
When all forces are balanced, the object can either be moving at a constant velocity or be at rest. But because you asked for balanced forces on a moving object, it is moving at a constant velocity.
When no outside forces act on asystem of objects what do the objects do?
If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.
What is it called When an objects speed is not changing?
Terminal velocity if it has reached its top speed. Or obviously constant speed.
What word is used to show an objects tendency to remain at rest or keep moving with constant velocity?
Inertia
