5. What is required to cause acceleration?

1 answer:

7 0

Answer: Acceleration is the rate of velocity of an object changing within time.

An object's acceleration is the result of all forces acting on the object, as described by Newton's Second Law.
It states that the acceleration of an object is dependent upon two variables: the net force acting upon the object and the mass of the object.

Why do you think it would be more practical to use an electromagnet to move scrap metal than to use a permanent magnet?

Answer:

#See solution for details.

Explanation:

-An electromagnet's field can be rapidly changed by just controlling the amount of current. The magnetic strength can be varied over time.

-This way, only a sufficient amount of current will be supplied to meet the needs.

-Unlike the electromagnet, the permanent magnet has a fixed magnetic strength and can only lift a specified weight.
