Answer:
D.) will not move unless acted on by another force
Explanation:
This is well-explained by Newton's first law, also called "Law of inertia", which states that:
"an object in state of rest (or in state of motion with constant speed) will remain at rest (or will continue moving with constant speed) unless acted upon an unbalanced force".
In the situation described in the problem, we have a bowling ball at rest on the table. The ball is acted upon two balanced forces: the force of gravity, downward, and the normal reaction of the table, upward. According to the First Newton Law that we mentioned above, the ball will remain in its state of rest unless it will be acted upon another unbalanced force that can accelerate it.
Answer: He didn't invent printing. He didn't even invent movable type. He often ran into legal trouble and, when he died in 1468, he did so with little money or glory.
Explanation:
Answer:
False
Explanation:
It is a vector because of the acceleration being a vector. F=ma.
Answer:
