What else can I help you with?
Does friction have force?
Yes,friction have force because if there is no force then friction cannot take place. Force is a thing 1.from which we can move from rest 2.from which we can change the state of motion 3.from which we can change the shape of an object 4.from which we can change the direction of motion of an object 5from which we can the speed of an object
Does the inertia of an object of an object change as its velocity changes?
No. Intertia is a measure of how easily an object's speed can be changed. So if it takes a certain amount of force or energy to speed an object up to a given speed, it'll take the same force/energy to slow it down to zero again, or it'll take the same energy to double its speed from that given level. Hope that makes sense.
When an unbalanced force acts on an object what does the force do?
It causes it to accelerate, according to the equation, Force = mass * acceleration. Force should be thought of as the Rate of Change of Momentum of an object. Specifically F=dP/dt. Take the equation F= ma = mdV/dt = d(mV)/dt =dP/dt
When a force on a object increases how does the objects acceleration change?
All objects possess the characteristic we refer to as mass. Mass is a measure of an object's natural resistance to any force applied to it. An object may be considered as having a velocity with respect to a given reference frame. This velocity can take any value from zero to just under the speed of light. If an object experiences an applied force, that force will cause the object's velocity to change. The change is at a rate and direction that is absolutely dependant on the direction of the applied force with respect to the original direction of motion of the object. If the applied force increases then so does the rate of change of velocity. If the force and any increase is applied in a direction with the motion of the object, the result is a positive acceleration, causing an increase of speed - or velocity. If the force and any increase of that force is applied in a direction opposing the original motion of the particle, this results in a negative acceleration resulting in a decrease in the objects speed - or velocity.

What does it take to change an objects state of motion?
it takes an unbalanced force to change an object's state of motion
What happens to the motion of an object if you change the mass of the object but keep the net force constant?
If you increase the mass of an object while keeping the net force constant, the acceleration of the object will decrease. This is because acceleration is inversely proportional to mass when force is constant (Newton's second law). Therefore, the object will move more slowly or take longer to reach a certain speed.

How much force does it take to keep an object moving in a straight line at a constant speed?
To keep an object moving in a straight line at a constant speed, you need to apply a force equal to the force of friction or any other resistive forces acting on the object. This force is called the net external force and is equal in magnitude but opposite in direction to the sum of all resistive forces.
What is the Formula for Force required to accelerate an object to a predetermined speed?
There is no specific force required to accelerate an object to a predetermined speed. A smaller force will produce a smaller acceleration, so it will take longer to reach the desired speed. A larger force will produce a larger acceleration, so the desired speed will be reached sooner. But either the large or the small force, or any other force, will produce an acceleration, and cause the object to reach the specified speed sooner or later.
How is it possible to be moving in one direction even though the unbalanced force is in the opposite direction?
Perhaps you are thinking that the velocity should be proportional to the force, or something like that. That's not the way it works. It is the acceleration, not the velocity, that is proportional to the force, but it may take a while to change the velocity. If an object is moving in one direction and there is a force in the opposite direction, it may simply take a while for the velocity to change enough, so that it also moves in the direction of the force. For example, if you throw an object upwards, once you let it go, basically the only force acting on the object is gravity - which basically pulls it downward. Depending on the object's speed, it may take a while for the object to "turn around".
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
