B. Explain why it is more difficult to move an object at rest, than to keep an object moving
1 answer:
Answer:
because the static friction is higher than the kinetic friction
Explanation:
Inertia is resistance to motion. Object resist changing its current motion or the rest position. This is the Newton's first law of motion
apart from this as the graph shows , the force needed to move when object at rest is higher than the force to change the motion of a moving body . this is because
<em>static friction > kinetic friction</em>
- static friction is the friction acts on a object resting on a rough surface
- kinetic friction is the friction acts on an object when it is moving on a rough surface
