For an object to be in projectile motion and what force must be acting on it?
Gravity must be the only force acting on the object, to produce downwards vertical acceleration. There is no force acting in the horizontal direction because there is no acceleration.
Does acceleration occur if the force is outside a system?
For acceleration, there must be a net force on an object. The force can come from anywhere. Internal forces - between parts of a system - will not cause an acceleration of the system as a whole, i.e., of its center of mass; such forces come in pairs, and - considering the system as a whole - they cancel one another.
How do you convert acceleration units to velocity units?
To convert acceleration to velocity, you must integrate.Similarly, to convert velocity to distance, you must integrate a second time. This is why the distance covered by a projectile is a second order quadratic equation.
What can you do to accelerate an object faster if you can not increase the force?
Force is mass x acceleration so in order to increase the acceleration without increasing the force, you must decrease the mass.
What happens to the acceleration as you increase the mass?
As per Newton's first law of motion, if the applied force remains the same, an increase in mass will result in a decrease in acceleration. In contrast, if the acceleration were to remain the same when the mass increases, there must be a greater force applied.
How many ways are there are to produce acceleration in a body?
One. In order to cause a body to accelerate, it must be acted on by a resultant force. This law is known as Newton's First Law of Motion.

What are the three fundemental questions that every economic system must answer?
what to produce. how to produce. who gets it
Which is NOT a question an economic system must answer?
When to produce it. ^^ from Stars Suite.

What force must act on a body of mass 50 kg to produce an acceleration of 20m sec2?
Force = mass x acceleration F = ma F = 50 x 20 = 1000 Newtons

Is it true In order to produce a current there must be a change of the magnetic field?
no
What three questions determine a country's economic system?
There are three simple questions an economy of a country must answer. They are "what to produce," "how to produce," and "for whom to produce."
What is process focused system?
A productive system for custom products must be flexible . it must have the ability to produce according to customer or client specifications.
