Question

Define me Friction ?

For 9th class

Answer 1

$\huge \mathfrak {Answer:-}$

$\bold{Friction}$ is defined as the force that always opposes when a body moves over the surface of another body.

$\bold{Example:-}$

=> When a box placed on a rough floor is pushed, you find it difficult and more force is required to move it.

Answer 2

Fully Explained ⤵⤵⤵⤵⤵

⭐friction is a force.

⭐Friction is a force that resists the relative motion between two objects or materials.

⭐The causes of this resistive force are molecular adhesion, surface roughness, and deformations.

✨Friction is a force that holds back the movement of a sliding object. That's it. Friction is just that simple.

➡The force acts in the opposite direction to the way an object wants to slide.

⭐Examples :--

▶Rubbing both hands together to create heat.

▶ A sled sliding across snow or ice.

⭐There are four types of friction:

▶static,
▶sliding,
▶rolling,
▶ fluid friction.

✨ Static, sliding, and rolling friction occur between solid surfaces.

✨ Static friction is strongest, amongst all

⭕followed by sliding friction, and then rolling friction, which is the weakest.

✨ Fluid friction occurs in fluids

➡That are liquids or gases.
