why did the salt shaker stop moving?\na the salt shaker ran out of force.\nb the table exerts a force that is opposite to the salt shaker’s motion.\nc the table absorbs force from the salt shaker.\nd all objects stop moving because their natural state is to be still.
Answer
Brief Explanations:
When an object like a salt - shaker moves on a surface like a table, it experiences friction. Friction is a force that opposes the motion of an object. Option a is incorrect as force is not something an object "runs out of" in this context. Option c is not correct as tables do not absorb force in the way described. Option d is wrong because an object's natural state is not always to be still (Newton's first law: an object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force). The table exerts a frictional force opposite to the salt - shaker's motion, causing it to stop.
Answer:
b. The table exerts a force that is opposite to the salt shaker’s motion.
