A feather falls slower than a marble due to air resistance or drag. The light and flat shape of the feather encounters more air resistance, which slows down its fall compared to the denser and more compact marble that falls faster.
You can make a feather drop slower than a marble by increasing air resistance. This can be achieved by attaching a larger surface area to the feather like a parachute, which will increase the drag force acting on the feather as it falls. Additionally, reducing the weight of the feather compared to the marble will also contribute to its slower descent.
The balloon falls slower than a marble because its buoyancy is greater and because its drag coefficient is greater.
A feather can fall more slowly than a marble in air due to differences in their size, shape, and air resistance. The greater surface area of a feather compared to a marble causes more air resistance, which slows down the feather's fall. A denser object like a marble will fall faster than a less dense object like a feather because it overcomes air resistance more effectively.
Air resistance.
Heavier marbles have more mass, so they have more inertia and resist acceleration more than lighter marbles. This results in slower acceleration and slower rolling speed down a slope compared to lighter marbles.
A feather would fall faster on Earth than on the Moon due to Earth's stronger gravitational pull. The Moon has less gravity than Earth, so objects fall more slowly on the Moon.
A feather falls slower than a brick because of air resistance. The larger surface area of the feather allows more air resistance to act against it, slowing down its fall. The brick is denser and has a smaller surface area, so it falls faster due to less air resistance.
The most important contributor to the erosion of marble gravemarkers is acid rain. Normal rain erodes marble also, but at a much slower rate than acid rain.
A hammer falls faster than a feather when dropped on Earth because of gravity. Gravity pulls objects with mass towards the Earth at a constant rate of acceleration, regardless of their size or shape. Since the feather has more surface area and air resistance, it falls slower than the hammer, which is more dense and streamlined.
You should change your hypothesis if the results from your experiments do not match what your hypothesis predicted. For instance, you make a hypothesis that a feather will fall at the same speed of a bowling ball. You drop both at the same time a number of times. You see that every time the bowling ball falls at a faster speed than the feather. You would have to change your hypothesis since it doesn't match your results. Your new hypothesis would be that a feather falls at a slower rate than a bowling ball.
this is because of air resistance which increases with surface area of feather. however if there is no air resistance (only vacuum) both feather and ball will fall together.
