What is needed to make something move?
An outside force. An object at rest stays at rest unless acted on by an outside force.
Which is not a big deal involving force and motion?
a force acting on an object at rest causese it to move
A small force acting on a human sized object causes?
The object will move if the net force amounts to a greater momentum than the force that is keeping that object at rest.
How do forces change a movement of an object?
inertia affects it. A force can move anything depending on its strength. Inertia states that an object at rest wants to stay at rest, and an object in motion wants to stay in motion. They alter the courses and movement of objects that have less force than the force trying to move the object
What is the definition of unbalance force?
Unbalanced force is simply where forces are unbalanced. Unbalanced forces are where the net force of an object is not equal to zero leading to acceleration or deceleration. If friction is neglected on a car moving at 50kmh it's net force is equal to zero as it is moving at a constant speed without accelerating or decelerating
What force can cause an object at rest to move or it can accelerate an object that is already moving?
Any force.
What is needed in order to cause an object at rest to move or an object in motion to change the direction and speed?
A force.
What is needed in order to cause an object at rest to move or an object you motion to change its deirection or speed?
An unbalanced force.
What is needed to cause the object at rest to move or an object in motion to change the direction or speed?
Force, which causes acceleration
What cause an object to move?
Newton said an object at rest will tend to stay at rest until acted upon by an external force. An object is moved when another force is applied to it. Whether it be from change in potential energy or just direct change in momentum, another force is necessary to move an object at rest.
What is needed in order to cause an object at rest to move or an object in motion to change its directed or speed?
An outside force to act on it
What is needed in order to cause an object at rest to move or an object in motion to change its direction speed?
An outside force to act on 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 is unbalaced?
An unbalance force is one that is not opposed by an equal and opposite force operating directly against the force intended to cause a change in the object's state of motion or rest. Consider this little illustration: Object, O is at rest and subjected to a force from the left as shown: Let ====> represent the force to change the object's state of motion or rest on object. O This unopposed (unbalanced) force will cause the object to move to the right. ====> O Let O <==> O <========, the larger force coming from the right is unbalance by the one from the left. Thus, the object will move toward the left. The picture is more complicated that I can illustrate here because an opposing force my be impinging on the object from an angle. Overall, it is the "net" unbalanced force that will cause the object to move or change its state of motion.
