Yes. An object moving at all in any direction at any speed has momentum due to inertia.
Yes, it can. Initially, an object will be accelerating downward (with an acceleration equal to g - f, where f is the force of air resistance). During this period, mass is constant but velocity is continually increasing, so momentum increases as well. However, because f is dependent on v (the speed of the object relative to the air), at a certain velocity, the force of air resistance will equal gravity, and the object will stop accelerating (this velocity is known as "terminal" velocity). At this point, the object will fall with constant speed, and momentum will remain constant.
The object's mass and speed.
When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed.
If the mass is doubled,speed should be halved to conserve momentum.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.
determine if the momentum of an object moving in a circular path at constant speed is constant.
determine if the momentum of an object moving in a circular path at constant speed is constant.
If an object is at rest it has inertia, which has to be overcome to make it move. When an object is moving in a straight line at a constant speed it has momentum, which must be overcome to slow or stop the object
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.

Yes. An object moving in a straight line at constant speed has constant velocity.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
When the speed of an object remains the same - it does not increase or decrease - we say it is moving at a constant speed.
If the mass is doubled,speed should be halved to conserve momentum.
