Question

Explain why the sliding friction is less than the static friction?​

Answer 1

Answer:

Friction comes into play when irregularities present in the surfaces of two objects in contact get interlocked with each other. In sliding, the time given for interlocking is very small. Hence, interlocking is not strong. Therefore, less force is required to overcome this interlocking. Because f this reason, sliding friction is less than static friction.

Explanation:

The friction between the two surfaces is because of the interlocking of the irregularities of the two surfaces.

During sliding, contact points do not get enough time to get interlocked properly. Therefore, less friction. But, when the object is at rest, the surfaces interlock well, therefore friction is more. This explains why sliding friction is less than static friction.

Answer 2

Friction is defined as the force that prevents one solid item from moving across another. Friction comes in two forms: sliding friction and static friction.

Explanation:

• The resistance formed between any two items as they slide against each other is known as sliding friction.

• The frictional force that acts between the surfaces while they are at rest with regard to each other is known as static friction.

• Because it is easier to move an object that is already moving than an object that is at rest, sliding friction is slightly lower than static friction for given two surfaces.
