What is the horizontal force that must be applied to produce an acceration of 2.8 g for 1.2 kg puck on a horizontal friction free air table?
Where the question says "2.8 g", we understand that to mean2.8 times the acceleration of gravity = 27.44 m/sec2 .F = M A = (1.2 kg) x (27.44 m/s2) = 32.928 newtons
How do you calculate the horizontal force that must be applied to produce an acceleration of 1.8 g?
F = M A F = force M = mass of the object being forced A = the object's acceleration You want A = 1.8 G = 1.8 x 9.8 = 17.64 meters per second2 Fnewtons = (17.64) x (Mkilograms)
What is done only when an object moves in the direction of the applied force?
Not necessarily. In our atmosphere, of course, we have friction due to the object displacing air, or if it is moving on some kind of wheel we have bearing friction, wheels (or what-have-you) against the road surface, etc. If the path or speed of the object is changing, then there is a force acting on it. Like the space station orbiting the Earth.
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.
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.

What will the mass and acceleration produce if the applied force is constant?
If the applied force is constant, the acceleration will also be constant. To know the actual amount of acceleration, you divide the force by the mass.
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

A horizontal force acts a body that is free to move can it produce an acceleration if the force is less then the weight of that body?
Yes it can, and if less force is needed if you eliminate the possibility of friction. You can find many examples of this, but i think this is an excellent opportunity to devise an experiment and practice your scientific methods.

What does newtons 2nd law state?
Newtons 2nd law means that when force is applied on any object an acceleration is produced in the direction of force which is applied on it. The acceleration produced in the object is directly proportional to the force applied on the object i.e. if force increases then acceleration will also increase and the acceleration is inversely proportional to the mass of object i.e. if the mass of the body decreases then acceleration will increase. If force is represented by 'F', acceleration by 'a' and mass by 'm' then a is directly proportional to F a is inversely proportional to m
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.
The law applied force states that a body's change in mass is proportional to the amount of force applied to it?
There is no such law. Newton's Second Law states that: force = mass x acceleration So, more force will produce more acceleration. More mass will result in less acceleration. However, the mass of a body usually doesn't change - but you can use this law to compare the same force applied to different objects, of a different mass.
