Yes force is necessary to cause motion. If an object is at rest the net forces acting on it are zero so it will remain in that state. The same goes for a body which is in motion, so long as the velocity remains constant with time you will not feel an accelerating force. The force that you feel will come into play when you wish increase or decrease your velocity. In order to do this you must accelerate, which in turn generates the force that you feel. The momentum of a body is the product of its mass times its velocity. Force is equal to the mass of the body multiplied by the time rate of change of its velocity.
What else can I help you with?
What do you call a force that maintains motion?
It could be called superfluous. No force is necessary to maintain motion.
What is inward force necessary for circular motion to occur?
Centripetal Force
Would there have to be an Unbalanced force acting on moving object?
There would have to be an unbalanced force put an object in motion but once in motion no force is necessary for it to remain in motion
What is a force produced by a circular motion that causes something to accelerate?
Circular motion doesn't produce force. 'Centripetal force' is necessary in order to produce circular motion. Also, so-called 'centrifugal force' isn't a force at all.
Is friction necessary for motion?
No. Friction is just necessary for controlling motion.
What is necessary to describe motion?
Something has to either be pushed or pulled by force.
What is the role of the normal force in circular motion?
The normal force in circular motion acts as the force that keeps an object moving in a curved path by pushing against the force of gravity and providing the necessary centripetal force.
A net is necessary for an object to change its motion?
A net force is necessary for an object to change its motion, according to Newton's first law of motion. If the net force acting on an object is zero, the object will continue in its current state of motion (either at rest or moving at a constant velocity).
Describe what is necessary to cause motion?
Something has to either be pushed or pulled by force.
Is force necessary to change the speed or direction of a body?
Yes, force is necessary to change any motion of an object. The force can, for example be gravity or friction. Without these two factors, an object would continue moving in its original velocity (speed and direction) in eternity.
What type of motion that is force is necessary to make all object accelerate?
heat energy
What is the role of the normal force in centripetal motion?
The normal force in centripetal motion acts perpendicular to the surface and helps keep an object moving in a circular path by providing the necessary inward force to balance the outward centrifugal force.
