Why is there less drag if an object is moving slowly?
Drag is caused by air resistance and other frictional forces. I'll use air resistance to explain it. Air resistance is caused because an object moving through air has to push air molecules out of it's way, if an object goes faster then it passes through more air molecules per second, so of course the force of the drag increases. And if it goes slower it comes into contact with less per second. Hope that helps!
Why is rolling an object easier than dragging an object?
Less friction/drag .
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
When an object is released in a fluid is the drag force less than its weight before it reaches terminal velocity?
Why is less force needed to keep an object moving than to start the object in motion?
1). Because maintaining an object in motion requires no force, but causing a non-moving object to move involves acceleration which does require force. 2). Because kinetic friction is generally less than static friction.
What does the mass of an object tell you about its inertia?
An object with a large mass is harder to get moving and harder to stop than an object with less mass. I hope this helps

Describe a place where a falling object would feel less drag than it would in your classroom Explain your decision using the definition of air resistance?
If all other conditions (weight and size of the falling object, gravity) are the same, then in vacuum. Explanation - take the falling object to be a feather--> if you drop it in the classroom (which hopefully has some air left in it), it gently falls, moving from side to side (this is the drag, air forcing it to change direction) until it hits the floor. If the same is done in an air-free environment (vacuum), the feather falls straight down and faster, because there is no air to "disturb" it. Now I try to explain the same, taking into account the definition of drag: As drag forces are acting in the direction opposite of the moving object. Therefore, if all the conditions are the same, then in vacuum as the speed of the fall of the object is increased, therefore drag (acting in the opposite direction of the object) has be less than in the air-filled room.
Why do you have to exert extra force to get a heavy object moving and then have to keep applying force to keep it moving at constant velocity?
the heavier and the bigger the object the more force you need to use to keep it moving . the less weight and the smaller an object is the less force you need to use to keep it moving. it always depends on the weight of the object and the size of the object.
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
Describe a place where a falling object would feel less drag than it would in your classroom?
A falling object would have less drag than in a classroom in a low pressure environment (higher up) or in a space or a vacuum, but then it's not really falling. Hope this clarifies.

1). Because maintaining an object in motion requires no force, but causing a non-moving object to move involves acceleration which does require force. 2). Because kinetic friction is generally less than static friction.
What is the correct meaning of slowly?
Moving or proceeding with little or less than usual speed or velocity.
Making an object a special shape to reduce drag?
to reduce drag you must make your shape more streamlined and more aerodynamic this meaning reducing drag so that there is less resistance therefore creating speed
Will an object moving forwards at the same speed travel further on a planet with less gravitational pull?
Assuming other aspects of the scenario are the same, yes. The object on the planet with weaker gravity will accelerate more slowly toward the ground, so it will have more time to travel forward.
