What force opposes the downward motion of falling object?
Air resistance
Is water resistance contact or non-contact force?
water resistance is contact force.
What is the net force acting on a freely falling 1-kg ball if it encounters 2 N of air resistance?
The idea is to calculate the downward force of gravity, and then subtract the air resistance, since it acts in the opposite way. This assumes that the ball falls directly downward.
Is water resistance contact or non-contact?
water resistance is contact force.
Why do falling objects reach a terminal velocity?
When the force of friction due to air resistance at that speed becomes equal to the object's weight. At that point, the sum of the vertical forces on the object is zero, so it no longer accelerates.

Is water resistance a contact or non contact force?
Contact.

What force draws water downward through the ground?
gravity....
What air and water resistance?
Air resistance is that resistance when substance moves in air and it expresses a opposite force on it. However, water restinace is water when a substance moves thorugh water and it expresses and oppoisite force.
Why do falling objects reach a terminal velocity?
When the force of friction due to air resistance at that speed becomes equal to the object's weight. At that point, the sum of the vertical forces on the object is zero, so it no longer accelerates.
A free body diagram of a ball falling in the presence of air resistance would show A only a downward arrow to represent air resistance B a downward arrow to represent gravity C neither?
Neither. It would need a downward pointing arrow for the force of the acceleration due to gravity and a second arrow for the air resistance pointing up.
Does the speed of free fall affected by the density of the object?
No. When an object is in free fall it has a downward force (it's mass) and an opposite, upward force of air resistance.
What The downward force acting on an object in free fall is the force of?
If we neglect the effect of air resistance, an object is accelerating toward the ground at 9.8 m/s^2. When you determine an object's weight, you multiply its mass by this number. My point is that weight is the downward force on an object.
If a 500 N parachutist opens their chute giving an air resistance force of 900 N what is the net force?
If the falling parachutist has a downward force of 500 N, and the air resistance force is 900 N (negative), then the net force is:500 N - 900 N = -400 N So, the parachutist gets a net upward force, causing him to decelerate while continuing to move downward, due to gravity.
