Assuming zero friction, the object will increase in velocity as long as an unopposed force is applied.
So long as the net force has a magnitude to overcome the static friction (and is constantly applied once the object is in motion) then the object will accelerate with respect to the difference between the force of kinetic friction and net force.
Force is measured in Newtons ((kg*(m/(s^2)) which is mass*acceleration) so the equation for force is F=m*a. To find the acceleration, the net force, F, divided by mass, m, will leave you with Newtons/mass on one side of the equation and acceleration on the other (m/(s^2)).
Example:
A 2kg block is pushed with a net force of 6N in one direction on a horizontal plane. The static friction constant between the block and the surface is 0.3 and the kinetic friction constant is 0.1.
The block has a weight of 19.6N (mass*gravity) and will have a normal force of the same value (Fn=W). The force required to put the object into motion will be (static friction constant)*Fn, or 19.6N*0.3 = 5.88N. Since this number is less than the net force applied to the block, the block will begin to move.
From this point on, if the force is constant, the net force in that direction will be higher (as the kinetic friction constant is smaller than the static friction constant). The new frictional force will be 19.6N*0.1 = 1.96N. Thus, the net force in the direction of motion is 4.04N. (4.04N)/(2kg) = 2.02 m/(s^2). The block will be moving at 2.02m/s at one second, 4.04 at two seconds and so on.
What else can I help you with?
How does zero net force affect an objects state of motion?
Zero net force means there is no overall force acting on an object, thus the object will either remain at rest or continue moving at a constant velocity (Newton's First Law). This state of motion is known as equilibrium.
If a box is sliding along at a constant speed and the force of friction on the box is 100n what is the net force on the box?
If the box is sliding along at a constant speed, the net force acting on the box is zero.If the net force was not zero, the box would either be speeding up or slowing down.Non-zero net forces acting on objects cause the objects to accelerate. Therefore, if the net forces is not zero, the velocity of the object could not be constant.
What force would change if a parachutist opens the parachute during the fall What will happen to the net force and acceleration over time after that?
When the parachutist opens the parachute, the air resistance force will increase. This will reduce the net force acting on the parachutist, causing a decrease in acceleration over time. As the parachute slows the descent, the net force continues to decrease until the parachutist reaches a terminal velocity.
For a given value of net force what would increase acceleration for a system?
To increase acceleration for a given net force, you can decrease the mass of the system. This is because acceleration is inversely proportional to mass when net force is constant (F = ma). Alternatively, you can increase the net force acting on the system.
What is the net force on an 900 kg airplane flying with a constant velocity of 180 Moho north?
If its velocity is constant, then the net force on it is zero, regardless of its mass or speed.
What is true of the velocity versus time graph of an object receiving an applied net force?
The velocity versus time graph of an object receiving an applied net force will show a linear increase or decrease in velocity, depending on the direction of the force.
What must be present to change an objects velocity?
A non-zero net force on the body.
A net force acting on an object changes the objects what?
Direction or shape
Why you never see objects moving with constant velocity unless a net force is applied?
friction
How does the velocity of an object traveling in a straight line change if a nonzero net force acts in the same direction as the objects velocity?
If a nonzero net force acts in the same direction as the object's velocity, the object's velocity will increase over time. This is because the force accelerates the object in the same direction as its motion, causing it to speed up.
Does rolling friction always reduce the net force acting on against an objects motion to zero?
The net force will be zero only if the velocity is constant, which means acceleration is zero.
How does a change of velocity occur?
A change in velocity occurs when there is a net force acting on an object. This force can come from interactions with other objects, like friction or gravity. The change in velocity can either result in speeding up, slowing down, or changing direction.
Is an object's velocity always proportional to the force acting on it at that instant?
Not necessarily. An object's velocity can depend on various factors, including inertia, mass, and the net force acting on it. While an increase in force can lead to an increase in velocity, other factors can also influence an object's motion.
A feather with no net force on it maintains constant?
In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.
When an object has a net force acting on it what happens to its velocity?
When an object has a net force acting on it, its velocity changes. The object will accelerate in the direction of the net force if the force is in the same direction as the object's velocity, decelerate if it's in the opposite direction, or change direction if the force is perpendicular to its velocity.
If the net force on an object is zero will the objects motion change?
No, if the net force on an object is zero, the object will continue in its current state of motion (either at rest or moving at a constant velocity). The object will not accelerate or decelerate without a net force acting on it.
How does zero net force affect an objects state of motion?
Zero net force means there is no overall force acting on an object, thus the object will either remain at rest or continue moving at a constant velocity (Newton's First Law). This state of motion is known as equilibrium.
