Yes Shapes changes the friction because it changes the surface area among other things. speed affects it is the sense that the object would come in more contact with the air and so the faster it goes the more friction

Yes, an object's shape and speed can both affect the amount of friction it experiences. A larger surface area or a rougher texture can increase friction. An object moving at higher speeds can also experience more friction due to the increased force it exerts on the surface it is moving against.
Factors that affect fluid friction include the viscosity of the fluid, the speed at which the fluid is flowing, and the surface area and roughness of the objects in contact with the fluid. Additionally, the density of the fluid and the shape of the objects can also influence fluid friction.
Magnetic friction can either attract or repel objects, which can slow down or speed up their movement. This friction is caused by the interaction between magnetic fields and the objects, influencing their motion.
Friction opposes the movement of objects by generating a force that resists the motion. It can cause objects to slow down, come to a stop, or require more energy to maintain their speed. Overall, friction reduces the efficiency of movement.
The rate at which objects roll down a slope depends on their mass, shape, and surface area in contact with the slope. Objects with less mass, a more streamlined shape, and less friction with the surface will roll down faster due to lower resistance to motion.
Gravity pulls objects towards each other, causing them to accelerate downward. Friction opposes the motion of objects in contact with one another, creating resistance. Together, gravity and friction can influence the speed, direction, and stability of moving objects.
