Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick. The air is actually an upward
force of friction
, acting against gravity and slowing down the rate at which the feather falls.
What causes a feather to fall more slowly than a penny?
Since the feather is so much lighter than the coin, the air resistance on it very quickly
builds up to equal the pull of gravity
. After that, the feather gains no more speed, but just drifts slowly downward.
What causes objects to fall slowly through the air?
When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object. The frictional force from a fluid is called a drag force.
Friction drag force
causes objects to slow down as they move through a fluid, such as air or water.
Can a feather reach terminal velocity?
As the feather falls, its air resistance increases until it soon balances the weight of the feather. The feather
now falls
at its terminal velocity. … In fact, it probably hits the ground before it reaches its terminal velocity.
When an object moves in a circular path it accelerates toward the center of the circle as a result of ?
| A B | centripetal force When an object moves in a circular path, it accelerates toward the center of the circle as a result of _______. | air resistance The upward force exerted on an object falling through air is _____________. |

Why does a feather and a rock fall at the same rate?
Well, it’s because
the air offers much greater resistance to the falling motion of the feather than it does to the brick
. … If a feather and a brick were dropped together in a vacuum?that is, an area from which all air has been removed? they would fall at the same rate, and hit the ground at the same time.
Do heavier objects fall faster?
Acceleration of Falling Objects
Heavier things have a greater gravitational force
AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
What might happen if there is no gravity 5 examples?
Humans and other objects will become weightless without gravity. If we have no gravity force, the atmosphere would disappear into space,
the moon would collide with the earth
, the earth would stop rotating, we would all feel weightless, the earth would collide with the sun, and as a consequence. We would all perish.
What slows down a falling object?
Air resistance (also called drag)
slowed down the heavier piece. Drag opposes the direction that the object is moving and slows it down. … If there were no air, the two objects would hit the ground at the same time. To slow down a fall of an object, you will want to create more drag.
What force acted on the objects as they fell on the floor?
The force of gravity
causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity.
Do heavier objects reach terminal velocity faster?
heavy objects will have a
higher terminal velocity than light
objects. … It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects.
Which reaches terminal velocity first?
Since blue’s weight is less,
blue
attains terminal velocity first. (Note that as they accelerate, R increases, because speed increases but after terminal speed reached, R is const.)
When a falling object reaches terminal velocity the force of gravity the force of air resistance?
At terminal velocity,
air resistance equals in magnitude the weight of the falling object
. Because the two are oppositely directed forces, the total force on the object is zero, and the speed of the object has become constant.
What must be true of a force that causes an object to move in a circular motion?
What must be true of a force that causes an object to move in a circular motion?
It acts parallel to the velocity and is directed toward the center of the circle.
What is the upward force exerted on an object falling through air?
| Question Answer | The upward force exerted on an object falling through air is Air resistance | When an object moves in a circular path, it accelerates toward the center of the circle as a result of Centripetal force |
|---|
What is acceleration toward the center of a curved or circular path called?
Centripetal Force
When a ball goes around a curve, the change in the direction of the velocity is toward the center of the curve. Acceleration toward the center of a curved or circular path is called
centripetal acceleration
.
