Answer:
rubber ball
Explanation:
basically friction is caused by little electrical bonds at a molecular level. the ice had more bonds due to it being a cube rather than a ball which has one point of contact. this means less energy is needed to put the ball in motion than the ice cube.
The ice ball reaches the bottom first, when the sheet is then tipped up. In the given condition, the ball and the ice cube have the same inertia.
It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).
Mathematically, it is defined as the product of the coefficient of friction and normal reaction.
The ice ball reaches the bottom first, when the sheet is then tipped up. In the given condition, the ball and the ice cube have the same inertia.
Because the ice cube slides down with virtually no friction. Without friction, an object can easily slide with the more speed.
The ball is spherical in nature and a spherical surface is in more contact with the surface during the inclined motion.
Hence, the ice ball reaches the bottom first, when the sheet is then tipped up.
