If you are asking the rate of acceleration on a surface, than the larger the force of gravity is, the more it will affect the rate of acceleration. The amount of friction depends one many variables, one of which is gravity. The larger your force of gravity is, the larger the force of friction is. Because of this, the more the force of gravity is, than the slower the rate of acceleration is because of the larger force of friction, which would be acting against the rate of acceleration. Therefore, the force of gravity does affect the rate of acceleration.
It takes no force to 'move' an object. There are trillions of objects that are moving right now with no forces acting on them. It only takes force to 'accelerate' an object ... to change its motion, by changing its speed or the direction of its motion. force=mass*acceleration As mass increases, so does the force needed to change the object's motion.
The greater the acceleration of the object the larger the force that is acting upon an object. This can be proven by Newton's second law.
Intriguing, right? - The basic idea is that acceleration is a change in velocity over time; and velocity is expressed in meters per second. So if, for example, an object changes its velocity from zero to 5 m/s, within one second, you will have an acceleration of (5 m/s) per second, or 5 m/s/s, or simply. 5 m/s2. The "second squared" by itself has no physical significance, only as part of larger units, such as acceleration, force (equals mass x acceleration), work (equals force times distance), etc.
So simple. Right from the ratio of the force applied to the mass of the body.

No. Force = mass x acceleration.
Force. This is the right answer. Trust me.

Byt Newton's Second Law, the net force must be in the same direction as the acceleration - if the car slows down, the net force is backwards, and if the car turns right (assuming the speed doesn't change), the acceleration is to the right, and therefore the force is also to the right.
Not exactly, it can change a few degrees of its direction, but cannot change its velocity because if it stops, the force of motion that goes with it will demolish the car therefore it cannot change it's velocity.++++???? If you put the question in everyday language, it is asking "Can a car change direction while accelerating?"Yes it can, provided the driver is careful to keep the acceleration and instant speed within safe limits. I emphasise 'speed' because the direction hence velocity - a vector value - is changing.I have no idea of the point about the remark about stopping - the supposed consequences are fiction, and the question is about accelerating.
This question is very unclear. Under the right circumstances any force will cause a change in motion. Whenever the net force, in a given direction, on a body is greater than zero, that body will move.
There are several different equations that can be used to find acceleration. The right one to choose depends on what information is given or measured. Examples: -- You're given the mass of an object and the force acting on it. Acceleration = (force) divided by (mass) -- You're given the starting and ending speed of a car, and how much time it was moving. Average acceleration = (change in speed) divided by (time for the change) -- An object started out from rest. You're told how far it moved and how long it took. Average acceleration = (2 x distance) divided by (time squared)
By definition, if two things are proportional to one and other, they are connected by a multiplying constant. If F = m + a you would simple say F is a bigger than m and it would also require that force, mass and acceleration all shared the same dimensions and units. Clearly mass is a scalar and force and acceleration are vectors, so that is not the case. Also, if they shared the same dimensions, they would effectively be the same thing so F = m + a would be the same as F(total) = F(1) + F(2) which wouldn't tell us very much about the laws of physics at all. Also, you don't say force is proportional to mass times acceleration (it's EQUAL to mass times acceleration). It's either force is proportional to mass (in which case acceleration is the factor of proportionality) or force is proportional to acceleration (in which case it is mass).
