How is friction affected by gravity?

The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. read more

The force of friction eventually causes the sled to stop. the friction force partly cancels some of the gravity force pulling the sled down. These two forces affect many motions on Earth. So, it means the effect of gravity maybe reduced due to friction of molecules/particles in between. read more

It is affected by the static friction that is a part of sliding friction. If the force applied to a wheel is less than the force of static friction, the wheel will grip the surface and begin to roll. If the force is more than that of static friction, the wheel will slip. read more

In the same way, friction affects the total acceleration of an object, but it does not change the acceleration due to gravity. Gravity is pulling on the object with the same amount of force, regardless of whether any other forces are acting on object or not. read more

Forces (including gravity and friction) can affect the speed and direction of an object. Gravity Gravity is a force that always attracts or pulls objects toward each other without direct contact or impact. read more
