Some Forces do not involve physical contact between the bodies on which they act.

If an object is moving at a constant speed in a straight line,
then the sum of all the forces acting on it is zero.
positive and in toward the circle
Friction, gravity
Because it describes the aspects,motion,behaviour of nature regarding forces acting on objects and their reactions under the behaviour of those forces
Nothing will happen to the object's motion, it will continue along its path.
motion
If the force is acting in the opposite direction to the movement, the object will slow down and then accelerate in the direction of the force. Negative for
law of gravity and friction
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).
Forces that are equal in magnitude, opposite in direction and acting on the same object will not create a change in said objects motion.
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
because it is in equilibrium
Not balanced. The net force acting on the object is not zero.
Radial force doesn't work on orbit in circular motion.ÊCentrifical force is created by objects going in a circular motion, where as there can be no balance of the forces.
aeronautics
Viscous drag
Balanced forces do not alter the motion of objects.
If the group of forces acting on an object is unbalanced, the object's motion always changes. The change is called "acceleration".
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
The sum total of all the forces acting on the object is zero.
