What is the effect of a constant force on speed?
A force, applied to an object, will cause an acceleration, that is, a change in velocity. This may be an increase or a decrease in speed, or a change of direction.
When a force on an object increases how does the object's 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 must happen for an obect at rest to move or change its speed?
A force must be applied to that object according to Newton's First Law of Motion in order to change the speed and its direction.
What is an force that can cause an object to change its speed and direction.?
A basic physics answer for this is that a net force (or unbalanced force) will cause an object to accelerate, that is, cause the object to change its speed and/or direction.
What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
What is the effect of a constant force on speed?
A force, applied to an object, will cause an acceleration, that is, a change in velocity. This may be an increase or a decrease in speed, or a change of direction.
What must happen for an object to stop start change speed or change direction?
A net force must be applied to the object. That is, the vector sum of ALL the forces acting on the object must not be zero.

How does extra force affect an objects speed?
F=ma, according to Newton's laws, so some more force will accelerate the object (that is, change its velocity in the direction of the force) at a rate of F/m. Speed is just how fast the object is going, while velocity is a combination of speed and direction. If the force is applied in a direction opposite the velocity, the speed will decrease. If the force is applied in the same direction, it will increase.
How can a force change the motion of an object?
Since energy cannot be destroyed but transformed the force that has been applied to the object has to be expressed as a change in the objects properties, such as its state of rest, speed or direction of travel, temperature etc.
Will an object move at a faster speed when force is applied to it?
yes depending how much you applied

A force must be applied to that object according to Newton's First Law of Motion in order to change the speed and its direction.
How does a knife decrease the force or the distance?
Because the size of the objects determine the speed and force of the object, the smaller the object, the higher the speed and the less force is applied whereas a larger object will apply more force and less speed.

What changes the direction of a force?
Force changes either the speed or the direction of motion, or both.
What happens to an object that is moving at constant speed when a force is applied?
The object will change its velocity due to the acceleration a=f/m = dv/dt = cdv/dr.It may also change it's direction subject to the vector of the force.
