air resistance and friction in the bearings
Not necessarily. Forces can act on an object even if it is not in motion, causing it to accelerate or just balance out other forces. The net force on an object determines its motion, accounting for all forces acting on it.
Forces are considered balanced when all of the combined forces lead to no change in the motion of the object.
yes it depends if you push or pull if you do then thats motion
-- First of all, motion doesn't require any force.-- If the forces on an object are unbalanced, then the object's motion changes. Always.-- If the forces on an object are balanced, then the object's motion doesn't change.
All forces involve the interactions between objects, causing changes in motion or deformation. They are described by magnitude, direction, and point of application. Forces obey Newton's laws of motion and can be classified as contact forces or action-at-a-distance forces.
If the forces acting on an object are equal there is no motion (5N->O<-5N). If the forces are unequal there is movement (7N-->O<-5N).
it smels like you
Balanced forces describes when all forces on an object are equal. Unbalanced forces describes when the forces on an object are unequal, resulting in movement. Forces are balanced when the vector sum of all the forces acting on the object is zero, at which point the object will be at rest or be in motion with constant velocity. Forces are unbalanced when the vector sum of all the forces acting on the object is greater or less than zero, at which point the object will accelerate by either starting motion from rest, or changing its motion if it is already in motion, for example, by changing direction or speed.
forces acting on an object. These forces can be contact forces, such as friction or pushing, or non-contact forces, such as gravity or magnetism. Changes in motion can also occur due to changes in mass or acceleration.
a footballer uses forces when he's kicking the ball
Two forces that affect nearly all motion are gravity, which pulls objects towards the Earth's center, and friction, which opposes the motion of objects moving against a surface.
No, they do not.
