What else can I help you with?
Is friction required while standing straight?
No, friction is not required for standing straight. Gravity and the interaction between your body and the ground provide the necessary support to maintain an upright position without the need for friction.
Why standing friction is greater than sliding friction?
Starting, or static, friction is greater than sliding friction in general. Static friction requires force to be overcome as the object rests on a surface due to its roughness. The roughness is a bunch of small contact points under high stress that resists motion; once this resistance is overcome, the object moves and its velocity allows the surface to glide over the rough spots more easily . This sliding friction is thus a little lower than static friction
Is the coefficient of friction the same as when the block was standing on its larger (or smaller) end?
No, the coefficient of friction can vary based on the contact surface area and material properties of the block. When the block is standing on its larger (or smaller) end, the contact surface area and the weight distribution changes, which can affect the coefficient of friction.
How does friction help in standing?
Friction helps in standing by creating a force that opposes the downward force of gravity, allowing your feet to stay firmly on the ground. This frictional force prevents your feet from sliding out from under you, providing stability and preventing you from falling.
Can you stand up without friction?
No, it is not possible to stand up without friction. Friction is the force that enables us to maintain stability and prevent slipping when standing or walking. Without friction, there would be no resistance between our feet and the ground, making it impossible to stand up.

You are standing on a merry-go-round that is in motion what forces is keeping you from flying off?
Friction. Friction is a resistance to motion.

What is the difference between static and rolling friction?
static is standing still, and rolling is movement. static is the friction that prevents the object from moving, rolling is the friction that slows down the object while it is motion.
Is giving a hug sliding friction?
No. your not sliding when you give a hug you are standing or else sitting.

How were the blocks of a pyramid stuck together?
For the most part; gravity and friction. Which is why they're still (mostly) standing.
How do you estimate the size of force on a car standing still?
Through push and pull and the other force is friction
Why is it easy to slip on a wet floor?
because the water reduces friction between the surface you are standing on, and your feet.
What is kinetic friction and static friction?
Friction is the resistance to movement of an object pressing/resting/moving on a surface. It's not intuitively obvious but the standing still friction and moving friction are different. Assume you have a block of wood resting on a tabletop. The amount of force required to make the block begin to move (static friction) is greater than the force required to keep it moving (kinetic friction) after it has begun to move.
