How much horizontal force must be applied to a 1kg puck to make it accelerate on a horizontal friction free air table with the same acceleration it would have if it were dropped and fell freely?

The acceleration it would have if it were dropped and fell freely = g = 9.8m/s^2
F = ma
F= (1kg)(9.8m/s^2) = 9.8N

A horizontal force of 100 N pushes a box across a floor at a constant speed. what is the force of friction acting on the box?
If the horizontal velocity is constant, then the horizontal acceleration is zero,and the net horizontal force is zero.But if you are saying that the body was in constant motion and after that the force was applied, then the body will acccelerate because of the force. The net force applied on the body would be equal to the force applied to it when the body was in constant motion as here the force is in direction of the motion and hence the angle will be 0 giving the value of cos 0º as 1. Hence there would be no reduction in the net force
Plot the graph of force vs acceleration?
Acceleration is directly proportional to applied force. When acceleration increases, force also increases. If the force is tripled, the acceleration will also be tripled. Note that the mass must remain constant...
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
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.
What is acceleration if coefficient of kinetic friction is 0.15 and 730 N force is applied to 186 kg crate?
2.454731183m/s^2
When a force is applied to a body in what direction will the body accelerate?
Acceleration is in the same direction as the applied force.
How is friction related to net force on an object acceleration of an object a create sliding on a surface?
F net=F applied - F friction
How does a wheel and axle change force?
A wheel and axial eliminates energy expended in vertical displacement, you don't need to waste energy hold cargo up. A wheel and axial also eliminate (to a large degree) horizontal friction. Therefore most of the energy applied is used in horizontal acceleration.
What accelerate a force of 100 newtons cause if applied to a motorcycle with mass of 50 kilogram?
Acceleration is 2m/s^2
why does an object with less mass have larger acceleration?
Whenna given force is applied ,an oobject with greater mass will accelerate less

How much work is done with a force of 300 N for 750 m if the force of friction is 200 N?
The idea here is to multiply the force applied - the 300 N - by the distance over which it is applied. The force of friction does not affect the calculation. Note: Since the force of friction is less than the force applied, and if there are no other forces, the object will accelerate.
How does mass affects the acceleration of an object?
When a force is applied, mass and acceleration are inversely proportional. Newton's 2nd law, F=ma, says that if an equal force is applied to a larger mass, it will accelerate proportionally more slowly.

Acceleration is directly proportional to applied force. When acceleration increases, force also increases. If the force is tripled, the acceleration will also be tripled. Note that the mass must remain constant...
What happens to an object when force is applied to it?
In general, when force is applied on any object it is accelerated in the direction of the applied force.The equation for the force is F = m*awhere m = massa = accelerationTo consider gravity, we can re-write the above equation as F = m*gwhere g = acceleration due to gravity (the gravitational constant) There may be an occasion where the applied force on an object is insufficient to break the existing dry friction, and the object will not move. In this case, the static and dynamic friction components "conspire" to hold the object in place. If the applied force exceeds the dry friction, the object will begin to accelerate, and the static friction will disappear. These are fundamental aspects of the laws of motion, and you can use the link below to learn more.
A car is moving at a constant speed of 30ms the combined mass of the car and the driver is 1000kg if the driving force is 3000N what is the value of the frictional force?
If the car and driver are moving (along a flat horizontal surface) at constant speed, then there is no acceleration, and the net horizontal force is zero.The applied 3,000N must be canceled by an effective total 3,000N of friction.
