Question

1. does it require more force to start an object sliding or to keep it sliding? explain your answer.

Explanation:

When starting an object sliding, static friction acts. Static friction is generally greater than kinetic friction (which acts when the object is already sliding). So, more force is needed to overcome static friction initially.

Answer:

It requires more force to start an object sliding. This is because static friction (acting when starting) is greater than kinetic friction (acting when keeping it sliding).
