Not necessarily. A constant net force will produce a constant acceleration, that is, the car will continue going faster and faster.

When the net force is not zero what will an object do?
Accelerate. Using Newton's second law, Net Force = mass * acceleration rearranged the equation acceleration = Net Force/mass so when the force is non zero and the mass is non zero, the object will accelerate. Note: This does not mean that the object is always at rest when the force is zero, it simply means the velocity is constant (when velocity =0, the object is at rest).
According to Newton's First Law we know that if an object at rest begins to move what must have happened?
A force must have been applied, no force no acceleration.
What are some examples of newtons second laws?
A moving car will slow down and eventually stop unless the engine continues to provide force to accelerate it.A car will remain at rest until it exerts a force upon the Earth greater than the car's weight.A parachutist at terminal velocity will not accelerate up or down, only remain at constant velocity.A rock moving through space will travel perfectly straight unles acted on by gravity (which is certain, of course).
When earth angular velocity increase then gravitational acceleration increase?
Let's be very accurate when describing accelerations in this question. Consider a person at the equator. The gravitational force of attraction on him is constant whether or not the earth is rotating. This acceleration is called the acceleration due to gravity (ag) Now, since the earth is rotating about its axis, there has to be a centripetal force on the person. It is the gravitational force which provides the centripetal force. Thus, there is a centripetal acceleration on the person (ac) Finally, the rest of the gravitational force causes the person to accelerate towards earth. This is called the acceleration of free fall (af) This gives ag = ac + af ac is given by the equation: ac = w2r where w is the angular velocity and r is the radius of rotation If the angular velocity of the earth increases, centripetal acceleration will increase. af = ag - w2r Therefore, the acceleration of free fall will decrease.
Do force exist to object at rest?
There CAN be, as long as the force is being counterd by an equal and opposite force.
How the unbalanced force affects the object at rest?
An unbalanced force will always make an object accelerate. If the object is at rest, it will start moving.
What force can cause an object at rest to move or it can accelerate an object that is already moving?
Any force.
When the net force is not zero what will an object do?
Accelerate. Using Newton's second law, Net Force = mass * acceleration rearranged the equation acceleration = Net Force/mass so when the force is non zero and the mass is non zero, the object will accelerate. Note: This does not mean that the object is always at rest when the force is zero, it simply means the velocity is constant (when velocity =0, the object is at rest).
How the forces affects the object at rest?
An unbalanced force will always make an object accelerate. If the object is at rest, it will start moving.
When a constant force acts on a mass starts moving from rest then the?
The object continues to accelerate as long as the force stays constant.
What happens to a body originally at rest when force is applied on it?
When force is applied on a body originally at rest, the body begins to move. For example, a car originally at rest when pushed, begins to move. A grass roller when pulled begins to move. A ball lying on the ground moves when it is kicked.
What causes an object for accelerate?
A force acting on an object will cause it to accelerate. This is one of Newton's Laws. Summarized as No force means no acceleration (the object will remain at rest, or will keep traveling with constant speed and direction until a force acts upon it).
How do balanced and unbalanced forces affect an object at rest?
they cause the object to move with acceleration given by A nett force.
What must be applied to an object to change its motion or direction?
If an object is at rest, a force must be applied to accelerate it (start it moving).
What happens to a charged particle at rest in the magnetic field Does the particle accelerate?
The particle stays at rest a= f/m = 0; because force = qvB is zero if v=0.
A body at rest tends to stay at?
Rest. At rest denotes a constant velocity including velocity of zero. Newton's Law says that a body will change its velocity ,accelerate or decelerate, only when an external force is applied. No force, no acceleration, no change in velocity. At rest itself denotes no force.
According to Newton's First Law we know that if an object at rest begins to move what must have happened?
A force must have been applied, no force no acceleration.
