The feather falls slower because it has air restistance. The air pushes up on it. The rock falls faster because it's mass and how it doesn't have air resistance. Also, because toilet seats produce a gas, reacting with the feathers on a feather, making the feather rise.
This is due to the force of viscosity, or better understood as air friction. It is the reason that any object will eventually stop speeding up and reach a terminal velocity. This viscosity force is often described as an expansion: F= av + bv^2 + c v^3 and so forth. Often this is approximated and the only term used is av. For a sphere falling under streamline conditions a=6*pi*viscosity*radius of the sphere. Hope that helps.
if you put force on an object, in the opposite way it is moving. force makes an object with mass accelerate. if the force you put accelerates it enough it will stop spontaneously, or else it will stop slowly. if that first type of motion was created by force, and i mean the force is still forcing the object to move, then u have to put more force to the object in the opposite direction in order to stop it. F= m*a where F = force , m= mass , a= acceleration hope u got ur answer
Fish swim upstream by powerfully thrusting their tails to counteract the current. They are then able to slowly but surely travel upstream.
the name of the force is called friction
By increasing productivity and reducing the force, a machine makes work easier. They also last longer than people and do not require pay.
Air resistance.
Gravity is the force which makes a thrown ball fall back to the ground. It is the force which attracts all objects to the Earth.
The force that makes things fall to the ground is called gravity. It is a natural force of attraction that pulls objects towards each other, such as the Earth and objects on its surface.
force of gravity
Newton reasoned that the force of gravity pulling the apple towards the ground was the unbalanced force causing the apple to fall.
It's true its called gravitytrue
A stick typically makes a scraping or grinding sound when it is being used to make a hole in the ground, especially if the ground is hard. The sound will vary depending on the type of soil and the force applied to the stick.

Every object has a (small) gravitational force that attracts other objects. The proportion of the Earth - human is so large that we sense this attraction force of the Earth. Gravity is the force which makes our feet stick to the ground!
Yes, a force is needed to make the golf ball bounce up after it hits the pavement. When the ball makes contact with the ground, the ground exerts an upward force on the ball, causing it to bounce back up. This force is known as the normal force.
