Why force changes the speed of an object?
Force = Mass * Acceleration or Acceleration = Force / MassThe Mass is the mass of the object and the Acceleration is the change of speed of the object due to the Force.
What mean acceleration?
acceleration= force/mass and also change in direction,speed are acceleration
Is the force the speed?
Force is not speed. Force is what makes an object change its speed. In other words force produces acceleration, which changes speed. The exact relation is given by one of Newton's laws of motion f=ma you can rewrite this as acceleration= force / mass
A change in speed or direction?
A change in speed or direction is caused by a force and is called acceleration.
How speed increase by applying force?
Applying more force in the direction of travel will increase the acceleration and therefore speed. If more force is applyed opposite to the direction of travel, acceleration will decrease.
Why does a car need force when its going at a low speed?
Force is any influence that allows an object to undergo change. Force is also Mass x Acceleration, and acceleration is a change in velocity. Therefore, the more force you have, the more positive acceleration you have, and therefore the higher the speed.
How is change in speed related is force and mass?
Force equals mass times acceleration. To change a speed, you must apply some force (either positive or negative) to give the object some acceleration. How quickly the object's speed changes will correspond to the force given divided by the mass of the object. (ie, the acceleration)

What is related to force?
mass, acceleration, motion - speed and velocity, newtons 1st law force = mass * acceleration speed requires force to change force acts on velocity to change it newtons 1st law describes force
A car is moving with constant speed and yet the acceleration and net force are not equal to zero how is this possible?
It's not possible. Acceleration is defined as a change in velocity, so if the speed is constant, the acceleration is zero. If the acceleration is zero, so is the net force.
What forces affect the speed and rate acceleration?
The force on a body determines its acceleration, speed depends on how long the acceleration lasts. Wind resistance and road friction (or other mechanical drag) will affect the power required to maintain a certain speed.
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.
